virtualenv is a tool for creating isolated virtual python environments. From 21.14.9 until 21.14.13, the bash bin/activate script can copy an attacker-controlled --prompt value into PS1 without escaping dollar signs or backticks when both promptvars and POSIX mode are disabled during activation. Re-enabling promptvars, running set -o posix, or starting an interactive child bash that inherits the exported PS1 can then expand command substitution in the stored VIRTUAL_ENV_PROMPT value and execute commands as the user who activates the environment. This issue is fixed in version 21.14.13.
pypdf versions prior to 6.21.2 contain a vulnerability where repeated malformed cross-reference entries can cause excessive resource consumption by triggering complete PDF stream reloads during recovery attempts. This issue leads to long runtimes when processing crafted PDF files. The vulnerability is fixed in version 6.21.2.
A vulnerability in the pypdf library prior to version 6.21.2 allows an attacker to craft a PDF file with a cross-reference table declaring more entries than the file actually contains. This causes the library to perform excessive iteration, leading to long processing times when opening the file. The issue is addressed in version 6.21.2.
pypdf versions prior to 6.21.2 contain a vulnerability where an attacker can craft a PDF that repeatedly references the same nonexistent indirect object. This causes repeated full-file recovery loads and long runtimes when accessing certain file parts such as pages. The issue is fixed in version 6.21.2.
An incomplete list of disallowed inputs in the Python code validator of the run_script tool in AWS MCP Server might allow an authenticated remote user to execute arbitrary code within their own isolated session environment via a crafted script.

CriticalExploitedMirageEPSS 99%Palo Alto Unit 42CVE-2026-109618
Two critical remote code execution vulnerabilities, CVE-2026-109618 and CVE-2026-109619, affect PHP, a widely used scripting language for web servers and CMS systems. Both vulnerabilities involve improper handling of memory during fatal error processing with longjmp(), allowing attackers to execute arbitrary code remotely. CVE-2026-109618 arises from uninitialized request memory after out-of-memory errors, while CVE-2026-109619 involves global memory pointing to freed regions that can be exploited in subsequent requests. Over 22.6 million exposed instances potentially vulnerable have been identified. Palo Alto Networks provides protections through multiple security products and recommends immediate patching. At least one European government took precautionary measures by taking its website offline. Users should review the PHP Group’s security advisory for patching guidance.
Microsoft Teams will introduce an AI-powered, context-aware phishing detection feature starting in early November 2026. This feature aims to identify phishing, social engineering, impersonation attempts, and deceptive intent by analyzing conversation context, particularly focusing on external first-contact chats. The system does not retain message content for AI training or other secondary uses and requires no action from IT administrators to enable. This enhancement is part of a broader set of security improvements in Teams designed to reduce phishing and fraud risks.
A potential security vulnerability has been identified in HP One Agent for certain HP PC products, which might allow for escalation
of privilege and/or arbitrary code execution. HP is releasing software updates to mitigate the potential vulnerability.
The LiteLLM 1.107.0 Python package was compromised and published to PyPI, distributing malicious code that executed automatically during Python interpreter startup. The payload collected a wide range of credentials including developer, cloud, browser, SSH, and environment variables, then encrypted and exfiltrated this data to attacker-controlled endpoints. The compromise originated from stolen developer GitHub credentials used to alter the release workflow. The malicious code executed without requiring explicit import of LiteLLM, affecting any environment where Python was started with the compromised package installed. Recovery requires more than removing the package; affected Python environments, running processes, and exposed credentials must be addressed. Microsoft Defender provides detection and hunting guidance. No patch or fixed version is explicitly stated.
CVE-2026-115569 is a path traversal vulnerability in the fallow-rs fallow codebase intelligence tool for TypeScript and JavaScript. Versions from 2.68.0 up to but not including 3.34.0 allow attacker-controlled Jest and Vitest project paths to reference files outside the project root via absolute paths, parent directory segments, wildcard globs, or symlinks. This causes fallow to parse external files as test-runner configurations, potentially affecting dependency and file usage analysis. The vulnerability does not expose file contents externally. The issue is fixed in version 3.34.0.
CVE-2026-115813 is a server-side request forgery (SSRF) vulnerability in AWS Multi Model Server version 1.1.11 and earlier. This flaw allows remote attackers to send requests to internal network destinations by exploiting the model download path with a crafted URL. The product is end-of-life with no fixed version available. Users are advised to discontinue use and migrate to supported model serving solutions. The vulnerability has a medium severity with a CVSS score of 5.8.
Relative path traversal during model archive extraction in Amazon Web Services Multi Model Server 1.1.11 and earlier might allow remote actors to execute arbitrary code via a crafted model archive.
Multi Model Server is end of life and no fixed version is available. Users should discontinue use of Multi Model Server and migrate to a supported model serving solution.
Two critical unauthenticated remote code execution vulnerabilities in PHP, collectively known as PHP2Shell, were publicly disclosed in October 2026. These vulnerabilities have a high severity score (CVSS 9.2) and affect PHP's memory management, enabling reliable exploitation when chained. The disclosure triggered immediate emergency responses from criminal forum operators, who took their platforms offline, migrated infrastructure, and restricted new registrations to mitigate risk. These forums store sensitive data such as member identities, private communications, and stolen credentials, making the vulnerabilities a significant threat to their operations. The adversary economy's reaction mirrors legitimate enterprise incident response, highlighting the severity of the vulnerabilities. No specific affected PHP versions are detailed in the provided data.
A race condition vulnerability (CWE-362) exists in tokio-rs tokio version 1.54.0 involving improper synchronization between tokio::time::Interval::poll_tick and the multi-threaded runtime's time driver. This can cause use-after-free issues leading to assertion panics, task reference-count corruption, or heap memory corruption. The issue is fixed in version 1.54.1.
A flaw was found in Kruize Autotune. Its REST API ships without an authentication layer, and the endpoints that return datasource configuration — the list-datasources endpoint (GET /datasources) and the datasource-metadata endpoint — serialized datasource objects using a default Gson configuration with no field-exclusion strategy. As a result, the authentication secrets stored for each configured monitoring datasource (basic-auth passwords, bearer tokens, API keys, and OAuth2 client secrets) were returned in cleartext to any client able to reach the service. An attacker with network access to Autotune could harvest these credentials and reuse them to authenticate to the backing monitoring stack.
Microsoft announced that Windows Server 2016 will reach its end of support in January 2027, after which it will no longer receive security updates or patches.

The PyPI package 'sitecard' versions 0.1.0 through 0.1.14 contains malicious code that creates an SSH session exposed via tunnels. This session is accessible without any authentication by default and reports to a hardcoded location, effectively acting as a backdoor. This exposes users to unauthorized remote access by attackers.
University Hospital in Ohio has taken its IT systems offline after detecting unusual server activity indicative of a potential security breach. The incident was reported on October 23, 2026, and involves the hospital's digital services being shut down as a precautionary measure. No specific technical details or confirmed exploits have been disclosed at this time.
A flaw in Node.js TLS hostname verification can cause a server certificate to be validated against a different IP address than the one the client connected to, when the host is a non-canonical IPv4 literal with a leading zero, such as `0127.0.0.1`.
`tls.checkServerIdentity()` normalizes the host following the WHATWG URL rules, which read a leading-zero octet as octal (`0127.0.0.1` becomes `87.0.0.1`), while the connection is made through the operating system resolver, which on some platforms such as macOS reads it as decimal (`127.0.0.1`). A server at the connected address can then be authenticated with a certificate issued for another IP address.
This vulnerability affects Node.js **26.x**, **24.x**, and **22.x**.
