A pickle deserialization vulnerability (CVE-2026-14890) exists in the SGLang open-source framework's expert-parallel backup subsystem. This vulnerability allows unauthenticated remote code execution if the subsystem is enabled and reachable over the network. The issue arises because a ZeroMQ PULL socket binds to an external IP without authentication or deserialization safeguards, allowing malicious pickle payloads to be processed. No patch is currently available, and the maintainers have not responded to coordination efforts. Mitigations include disabling the pickle IPC feature and restricting network access to the vulnerable interface.

MappedImagesDetector is an open-source Windows memory scanner tool designed to detect manually mapped DLLs and suspicious in-memory images that evade traditional antivirus detection. It inspects process memory directly, identifying anomalies such as erased PE headers, fake import address tables, and executable regions not registered with the Windows loader. The tool uses heuristics focusing on import thunk patterns to detect manually mapped images. It is intended for antivirus, EDR developers, blue teams, and malware researchers to improve detection of in-memory malware techniques. This project is research-focused and not an offensive tool.

Anthropic’s new AI agent for Slack acts under an admin-configured access bundle rather than each user’s own credentials. Here’s how that model works, what admins should understand and how to securely configure it. Key takeaways Claude Tag, Anthropic’s newly launched AI agent for Slack, acts on connected services using shared credentials an admin configures for a workspace or for a specific private channel, not the credentials of the user tagging it. Claude Tag uses the service-identity pattern, like deploy bots, workflow automations, and incoming webhooks, rather than per-user OAuth delegation. As a result, one admin-configured bundle serves everyone in the channel. Inviting someone to a channel where Claude Tag is present lets them converse with Claude and see its output there. What Claude can access is fixed by the admin-configured bundle, and organizations can require claude.ai login and role-based access control before a user may interact with Claude at all. Channel invitations do not confer new permissions on the invitee. As part of Tenable’s ongoing partnership with Anthropic, Tenable Research worked with their security team through coordinated disclosure. Claude Tag lets Slack channel members direct an agent whose reach is defined by the admin-configured access bundle. (Source: Tenable Research) What is Claude Tag? Claude Tag is a multiplayer AI assistant that lives inside Slack. With Claude Tag, which was released by Anthropic on June 23, 2026, anyone in a channel can tag @Claude to hand off tasks, run autonomous jobs over hours or days, and watch the work unfold in-thread. Claude Tag in a Slack channel, using the attached access bundle to read from a connected GitHub repository. The agent responds to any channel member within the bundle's scope. Source: Tenable Research. In a traditional 1-on-1 AI interaction, such as a chat UI, a command-line interface (CLI), or a Model Context Protocol (MCP)-connected app, the agent acts as you. Claude Tag keeps that model in direct messages: a DM runs on the sender’s own claude.ai account, using that user’s own connectors. In shared channels , however, Claude Tag is a multiplayer agent: It serves many users at once, and no single user’s credentials define its access . There, the agent is given its own identity, with its own permissions, configured once by an admin, and reused by everyone who tags it. The controls governing that access are: The admin’s bundle configuration determines what the agent can do The channel determines where it participates and what it can see Organization-level Claude Enterprise controls, such as required claude.ai login and role-based access control, govern who can direct it Claude Tag also differs from per-user Slack integrations . Slack’s own GitHub integration, for example, uses each user’s personal GitHub OAuth token. When a user runs /github in a channel, the integration acts as that user, and sees only what that user can see. The same is true for Slack’s Jira and Asana apps. Claude Tag works the other way: One shared credential applies to every user in the channel. For GitHub, that credential is a Claude GitHub App installation token scoped to a repository allowlist the organization owner configures. No individual's OAuth is used, and actions are attributed to the Claude app. Admins can restrict which repositories each channel can reach by attaching different bundles to different channels. For example, a finance channel can be scoped only to finance repos, while an engineering channel only to its own. For non-GitHub OAuth connectors (e.g., Google Drive), the bundle reuses the OAuth credential of the organization’s admin or owner who connected it. Claude Tag’s access model Claude Tag isn’t just a Slack bot; it’s an autonomous AI agent with its own identity, separate from any human user. When someone in a channel types @Claude, the assistant doesn’t act as that user; it acts as itself, using credentials provisioned by access bundles . The identity model for Claude Tag has three layers : A Claude Tag installation bound to a Slack workspace Access bundles that group connector credentials configured once by an admin, such as a Claude GitHub App installation for repositories, and OAuth-approved credentials for other services) Scopes that define which Slack contexts, such as a workspace or a channel, a bundle is available in. An access bundle configured attached to a single Slack channel. The bundle's scope is set by the admin, not by the users in the channel. (Source: Tenable Research) The trust boundary that admins can control is the scope. Attaching a bundle to a channel is an admin decision: Members of that channel can then direct Claude within the bundle’s scope. For example, they can scope a GitHub app installation to an allowlist of repositories, while for other OAuth connectors they can scope the credential of the admin who connected them. Claude Enterprise admins can additionally require users to log in to their claude.ai account and restrict usage via role-based access control (RBAC), under which non-qualifying users cannot start Claude sessions and their messages in existing threads are treated as untrusted. There’s no mapping from “the Slack user who typed @Claude” back to “what that user is allowed to access in the connected service.” The model also constrains users: Someone acting through Claude cannot bring their own privileges. Writes happen only where the agent is scoped to write, so they land in admin-chosen, visible locations rather than wherever an individual user’s credentials could reach. Anthropic’s documentation states the model explicitly. The attach-to-scope page warns: “A bundle attached to a public channel grants its access to anyone who joins that channel. In most Slack workspaces, anyone can join a public channel, so the channel’s join policy becomes the effective access control for whatever the bundle grants. Keep elevated credentials in private-channel scopes.” Security implications of multiplayer agents Slack channel configuration is now part of your access-control surface. Traditional application identity and access management (IAM) is per-user: Each person authenticates and is gated against their own identity in each system. An agent like Claude Tag instead has its own identity: the admin-configured bundle defines what the agent can reach, and the channel defines where it participates and who can converse with it. Adding a user to a channel lets them direct Claude within that admin-chosen scope; organizations can require claude.ai login and RBAC before a user may direct Claude at all. You should review bundle scope and channel membership together. Slack admins now make decisions that matter for access control. Attaching an access bundle to a channel determines what Claude can reach there. Review bundle attachments with the same rigor you apply to IAM changes, and use organization-level controls, such as required claude.ai login and RBAC) to bound who can direct Claude. Channel invites then govern who can converse with the agent within that admin-chosen scope. You should scope bundles deliberately and pair them with organization-level controls. Keeping elevated bundles in private channels narrows where the agent participates and who can converse with it. A new channel member can see prior scrollback and converse with Claude there, but what Claude can access stays fixed by the admin-configured bundle. The right practice is minimum-privilege bundles per channel, per task, combined with those organization-level requirements. Anthropic’s planned enhancements Anthropic has said publicly that it plans to strengthen Claude Tag’s security offerings with two additions (see Anthropic’s June 24 post, “ Agent identity in Claude Tag: a new access model ”): Just-in-time credential grants, where a user approves a single sensitive action in the moment without permanently widening the agent’s scope An identity-aware overlay, adding user-level checks on top of an agent’s scope for organizations with more complex clearance structures These are additive options layered onto the channel-scoped agent model, not a replacement for it: agent identity remains a first-class model, and organizations will be able to combine it with user-level checks, or rely on user identity alone for a given channel where it fits their needs.

Here are four actions you can take immediately to reduce the access risks they create: Audit your access bundles. For every Claude Tag bundle in your organization, identify the: connectors it holds credentials for scopes it’s attached to users who can direct Claude in those scopes today, making that set deliberate: manage channel membership, and use organization-level controls (such as required claude.ai login and RBAC) so only intended users can direct Claude. Review channel membership and bundle scope together. For channels whose bundles grant sensitive reach, route invites

It highlights challenges posed by isolated application security data and accelerated code deployment, especially with AI-assisted coding increasing vulnerability rates. The integration enables security teams to contextualize vulnerabilities within the broader organizational risk, prioritize fixes effectively, and provide CISOs with actionable risk metrics. It is not a specific vulnerability or exploit but a security management approach to reduce organizational exposure to code flaws.

Warp is an open-source browser-to-browser file transfer application that uses WebRTC and DTLS to enable end-to-end encrypted peer-to-peer file transfers. The server only acts as a signaling broker for connection setup and never sees or stores any file data. This design ensures that file contents remain private from the server, ISPs, and network intermediaries. However, Warp does not use TURN relays, so transfers fail if both peers are behind symmetric NATs that prevent direct connection. The signaling server does see metadata such as connection timing and IP addresses. The project is open source and can be self-hosted to verify the code and trust model.

Microsoft Corp. today released software updates to plug at least 570 security holes in its Windows operating systems and other software, almost triple the number of vulnerabilities the software giant fixed in its record-smashing Patch Tuesday release last month. Microsoft attributed the burgeoning patch counts to vulnerability discoveries aided by artificial intelligence. Nearly 60 of the bugs quashed in July’s Patch Tuesday earned a “critical” severity rating, meaning miscreants or malware could use them to seize remote control over a Windows device with little or no help from the user. Microsoft also addressed three zero-day flaws, including two that are already being exploited in the wild. Two of the zero-day weaknesses allow an attacker to elevate their user rights on a Windows system, as do approximately 250 other elevation of privilege flaws fixed this month; they include CVE-2026-56155 — an Active Directory Federation Services bug — and CVE-2026-56164 , a Microsoft Sharepoint vulnerability. CVE-2026-50661 is a security feature bypass in Windows BitLocker that could allow attackers to gain access to encrypted data if they have physical access to the device. Microsoft said this bug has been detailed publicly, but that it is not aware of any active exploitation. In a blog post on July 9, Microsoft Executive Vice President Pavan Davuluri wrote that Windows users will notice “a higher volume of security updates included in each security release” as a result of AI aiding in the discovery of vulnerabilities. “The pace of vulnerability discovery is changing with advances in AI making it possible to find more issues, faster, across more code, with new mechanisms that can accelerate both discovery and analysis,” Davuluri wrote . Jack Bicer , director of vulnerability research at Action1 , called attention to CVE-2026-48561 , a remote code execution flaw in Microsoft Copilot (with a 9.6 CVSS threat score) that allows an unauthorized attacker to execute code over the network. Microsoft says an attacker could exploit this bug by hosting a malicious website that causes Microsoft Edge for Android to automatically send crafted prompts to Copilot when a user visits the site. As AI advances the state of vulnerability discovery and remediation, it is also making it easier for attackers to quickly devise working exploits for known software flaws. Microsoft has long labeled security bugs using its “exploitability index,” which is Redmond’s best guess as to how likely it is that attackers will be able to figure out a reliable way to exploit a given vulnerability. But Satnam Narang , senior staff research engineer at Tenable , argues that Microsoft’s exploitability index needs to do a better job of shifting with the machine speed of discovery. For example, Microsoft originally gave this month’s SharePoint zero-day an exploitability rating of “less likely,” although the flaw was added to CISA’s Known Exploited Vulnerabilities list on July 1. “Anthropic’s Red Team’s own findings for known vulnerabilities (n-days) revealed how fragile this system has become, with its Mythos Preview model being able to produce proof-of-concept exploits for 13 of 14 vulnerabilities that were rated ‘Exploitation Less Likely’ or ‘Exploitation Unlikely,'” Narang said. “What this means is that our way of looking at Patch Tuesday has changed, because the exploitability index is centered around humans, not AI tools, and as these tools continue to improve, defense needs to improve alongside it.” Chris Goettl at Ivanti observed that the record patch numbers from Microsoft come as a number of other major software makers are increasing their patch cadence, including Adobe which announced today it is moving to twice-monthly security bulletins published on the 2nd and 4th Tuesday of each month (Adobe also cited AI for accelerating their patch cycles). Cisco , Mozilla and Oracle also are shipping updates more frequently, while Google’s patch batches in June 2026 totaled more t…

SAP released patches addressing multiple critical vulnerabilities in NetWeaver Application Server ABAP, Approuter, and Commerce Cloud. The most severe is a memory corruption flaw in NetWeaver that could allow data access, modification, and system unavailability. Approuter suffers from an HTTP request smuggling vulnerability causing request-response desynchronization. Commerce Cloud has a hardcoded credential issue in sample OAuth2 client configurations that could enable unauthorized data access if not remediated. SAP advises applying patches and auditing production environments for hardcoded credentials.

For years, the cyber security industry tracked AI as a force multiplier: something that made existing attack techniques faster, cheaper, and more accessible. That framing was accurate. But the Annual AI Security Report 2026 from Check Point Research documents a transition that goes further. AI has crossed from assistant to operator. Where it once helped attackers prepare, it now runs the operation. Key observed findings AI has crossed from development aid to live attack operator. It now does the hands-on work inside live intrusions, from China-nexus espionage campaigns to a criminal breach of multiple Mexican government agencies and has spread from nation states to ordinary cyber criminals. AI now builds deployment-ready malware and attack suites. Its involvement is often invisible in the finished artifact: one developer used an AI environment to produce VoidLink, an 88,000-line command-and-control offensive framework, in under a week. Attackers prefer commercial models, and now abuse them by exploiting the agentic architecture, not just single prompts. Most actors favor jailbroken mainstream models over self-hosted ones, and the durable bypass is now a planted configuration file an agent loads and trusts across sessions. An AI-enabled criminal tooling market has matured. Phishing-as-a-service kits now embed a language model with the jailbreak built in, and conversational AI voice-agent services run vishing and one-time-passcode theft at scale. Virtual Identity is no longer a reliable trust anchor. Voice, face, documents, and live video are now cheap to forge convincingly and are widely used in attacks taking multi-channel social engineering to a new level of integration. AI itself is an expanding attack surface. Models cannot always separate data from instructions and content they process might influence the model’s behavior; the surrounding stack adds ordinary software vulnerabilities and supply-chain risk, all in a rapidly evolving ecosystem where security practices not always mature. Indirect prompt injection is on the rise. Detections of longer malicious payloads increased sharply, rising roughly fivefold between March and May 2026 and approaching 1% of observed prompts in May. Longer payloads are more typical of content-borne and agentic attack paths, this pattern suggests that indirect prompt injection is becoming more operationally relevant. Enterprise data leakage through GenAI is persistent and growing risk . High-risk prompts doubled from 2% to 4% during the last year, while organizations used an average of 10 AI applications each month, many without official approval. Data exposure risks are not evenly distributed across the verticals . Sector-level analysis reveals that AI-related data exposure risks are not evenly distributed across the verticals, and correlate both with AI usage patterns and security maturity. Business Services recorded the highest rate of high-risk GenAI prompts at 5.91%, meaning nearly one in every 17 AI interactions carried a significant risk of sensitive data exposure.

CISA has issued a warning about actively exploited remote code execution (RCE) vulnerabilities in two Joomla extensions: iCagenda and Balbooa Forms. These vulnerabilities allow attackers to upload arbitrary files, including executable PHP scripts, leading to full website compromise. The iCagenda flaw (CVE-2026-48939) affects the file attachment feature, while the Balbooa Forms flaw (CVE-2026-56291) affects the file upload functionality in contact forms. Both vulnerabilities were exploited in the wild before patches were released. Fixes are available in iCagenda versions 4.0.8 and 3.9.15, and Balbooa Forms version 2.4.1. CISA has mandated rapid patching for federal agencies due to the critical nature of these flaws.

For the latest discoveries in cyber research for the week of 13th July, please download our Threat Intelligence Bulletin. TOP ATTACKS AND BREACHES U.S. auto insurer AssuranceAmerica has disclosed a data breach affecting approximately 7 million people. Attackers targeted an employee and used compromised credentials to access company systems, stealing names, contact information, driver’s license numbers, insurance policy and account data, vehicle information, and claims details. Latvia’s state-owned forestry company Latvijas Valsts Meži has suffered a ransomware attack that disrupted mapping, hunting, contractor, and customer systems. Attackers exploited a system that had remained unpatched for two years and leaked approximately 44GB of internal documents, credentials, cryptographic keys, source code, and email correspondence. Injective Labs, a developer of blockchain and cryptocurrency software, has experienced a supply chain compromise after attackers accessed its SDK project and published malicious npm packages. The affected releases exfiltrated cryptocurrency wallet private keys and seed phrases when developers used legitimate key-generation functions embedded in the compromised software. Moody Bible Institute, a U.S. faith-based educational institution, has disclosed a data breach affecting more than 2.3 million donors, students, alumni, and supporters. The ShinyHunters extortion group published allegedly stolen information, including names, dates of birth, residential addresses, email addresses, and phone numbers. AI THREATS Researchers profiled JadePuffer, an autonomous ransomware operation that used a large language model to conduct an intrusion without direct human control. The operation exploited CVE-2025-3248 in an exposed Langflow instance, accessed a production MySQL server, exfiltrated selected information, deleted the database, and issued an extortion demand. Researchers showed that malicious instructions hidden inside open-source project files could achieve remote code execution through Anthropic Claude Code and OpenAI Codex. When operating with automated permissions, the coding agents processed the instructions and executed attacker-controlled scripts, demonstrating a risk that may affect other autonomous development tools. Researchers disclosed Rogue Agent, a vulnerability in Google Dialogflow CX that allowed users with limited agent-editing permission to insert persistent malicious code. The injected code could capture and exfiltrate chatbot conversations. Google addressed the issue, and no known customer environments were compromised through the vulnerability. VULNERABILITIES AND PATCHES Multiple Tenda router models are affected by CVE-2026-11405, an undocumented authentication backdoor that provides administrative access through a hidden password. The flaw affects several FH1201, W15E, AC10, AC5, and AC6 firmware versions and allows attackers to bypass configured credentials and modify device and network settings. Linux maintainers have patched CVE-2026-53359, a critical vulnerability in the Kernel-based Virtual Machine hypervisor. A malicious guest virtual machine could corrupt host kernel memory and potentially escape into the host environment. The flaw affects Intel and AMD x86 systems and is particularly relevant to shared cloud infrastructure. U-Boot has addressed six vulnerabilities affecting signature verification of Flattened Image Tree files used during secure boot. Two flaws could enable arbitrary code execution while a device loads a supposedly verified image, and four could cause crashes. The affected bootloader is widely used in routers, cameras, and embedded controllers. Opera has addressed a critical vulnerability in the Opera GX browser that allowed malicious websites to install browser modifications without user confirmation. An attacker-controlled modification could inject styles across open tabs, leak information such as Gmail addresses, and crash the browser. Opera corrected the issue. TH…
