Key takeaways: Two WordPress Core vulnerabilities, CVE-2026-63030 and CVE-2026-60137, can be chained together to achieve pre-authentication remote code execution against WordPress 6.9.x and 7.0.x installations. Multiple security firms have confirmed in-the-wild exploitation, with public proof-of-concept exploits appearing within hours of the July 17, 2026 disclosure. Patches are available in WordPress 7.0.2 and 6.9.5; WordPress.org has enabled forced automatic updates across affected supported installations. Background Tenable's Research Special Operations (RSO) team has compiled this blog to answer Frequently Asked Questions (FAQ) regarding wp2shell, two vulnerabilities in WordPress Core that can be chained together to achieve pre-authentication remote code execution. FAQ What is wp2shell? wp2shell is the name given to two vulnerabilities in WordPress Core. When was wp2shell first disclosed? On July 17, 2026, WordPress released security updates addressing the wp2shell vulnerabilities alongside two GitHub Security Advisories. Adam Kues of Searchlight Cyber, who discovered and disclosed CVE-2026-63030, published research on the same day and chose to hold back the technical specifics given the severity of the finding. Searchlight Cyber also launched wp2shell.com , a testing tool that allows administrators to check whether their WordPress installation is vulnerable. On July 20, Searchlight Cyber published a full technical breakdown of the attack chain. What are the vulnerabilities associated with wp2shell? wp2shell is a two-vulnerability exploit chain affecting WordPress Core. CVE Description CVSSv3 CVE-2026-63030 WordPress Core REST API Batch-Route Confusion Remote Code Execution Vulnerability 9.8 CVE-2026-60137 WordPress Core WP_Query author__not_in SQL Injection Vulnerability 5.9 CVE-2026-63030 is a REST API batch-route confusion weakness introduced in WordPress 6.9. CVE-2026-60137 is a SQL injection flaw in the author__not_in parameter of WP_Query , present in WordPress 6.8 and later. When chained on WordPress 6.9.0 through 7.0.1, the two flaws allow an unauthenticated attacker to reach the REST API batch endpoint at /wp-json/batch/v1 and achieve remote code execution. CVE-2026-60137 was discovered and disclosed by security researchers TF1T, dtro, and haongo. CVE-2026-60137 also affects WordPress 6.8.0 through 6.8.5 as a standalone SQL injection issue. Because CVE-2026-63030 was introduced in WordPress 6.9, the full RCE chain is only achievable on 6.9.x and 7.0.x installations. How severe is the wp2shell vulnerability chain? An anonymous, unauthenticated user can execute the chain against a default WordPress installation with no plugins required. No preconditions exist beyond the default WordPress configuration. Cloudflare notes that the vulnerable code path is reached when “a persistent object cache is not in use.” Note: wp2shell targets WordPress Core itself rather than a plugin or theme. All four prior WordPress-related entries in the CISA Known Exploited Vulnerabilities (KEV) catalog involve plugins, not core. Pre-authentication remote code execution in WordPress Core is uncommon.

Scammers have weaponized fake iPhone Duo preorder pages to deploy the DarkSword exploit chain against vulnerable iPhones. The fraudulent pages mimic Apple's design and offer a $500 voucher to lure victims, but simply opening the page in Safari triggers an exploitation attempt without requiring user interaction. The attack targets iPhones running unpatched iOS versions, attempting to bypass security protections and deploy a payload designed to steal saved credentials, cryptocurrency wallet data, notes, messages, contacts, and other sensitive information. The exploit leverages vulnerabilities previously disclosed by Google in March 2026 and patched by Apple. If successful, the payload establishes communication with command-and-control servers and can execute additional commands remotely while attempting to cover its tracks by deleting diagnostic reports.

A social engineering campaign targeting security professionals uses fake consultancy offers and job opportunities to exploit trust. Attackers create sparse social media profiles claiming to be consultants, offering $300 for simple consultations on topics like digital transformation. The initial phone call serves as screening to identify targets with valuable access or knowledge. If successful, targets are asked to provide increasingly sensitive information through written reports, requiring them to abuse trusted access, probe internal systems, or leverage professional relationships. Similar variants include fake recruiters offering prestigious positions while requiring installation of trojanised software. These attacks exploit professional flattery and overconfidence, manipulating security practitioners into compromising their most valuable asset: professional integrity and trusted relationships within the industry.

In early September 2026, Chinese threat actor UTA0565 exploited unpatched zero-day vulnerabilities in Google Chrome and Microsoft Windows through sophisticated phishing campaigns. The actor registered fake domains impersonating legitimate organizations including China Digital Times and the Center for American Progress, sending targeted phishing emails to Asian government entities. Victims were directed to spoofed websites hosting an exploit chain leveraging CVE-2026-85046, CVE-2026-87491, and CVE-2026-85880. The attacks delivered CLEANGULP, a previously undocumented malware family with backdoor capabilities including command execution, file operations, and beacon object file execution. The malware communicated with command-and-control infrastructure via encrypted HTTP traffic using custom encoding. Multiple Chinese APT groups demonstrated coordinated access to this exploit kit, suggesting widespread sharing within the Chinese cyber espionage community during the vulnerability window.

Settra is a ransomware variant first observed in June 2026 that targets organizations through VPNs or compromised credentials. Two incidents were investigated in July and September 2026, affecting the consumer services, retail, and manufacturing sectors. Attackers deployed MeshAgent RMM for persistence, naming ransomware executables after victim domain names. The malicious activity included file encryption with .locked or .locked_wip extensions, deployment of RESTORE_FILES.txt ransom notes, clearing Windows event logs, and disabling Windows recovery options using reagentc and diskpart utilities. One incident featured Bring Your Own Vulnerable Driver (BYOVD) tactics using gdrv.sys. A notable operational security failure occurred when attackers misspelled the Windows Defender Event Log path, preventing its deletion. Both attacks followed remarkably similar operational patterns, with MeshAgent installations pointing to different C2 IP addresses (45.13.122[.]7 and 193.5.65[.]114), and malicious workstation WIN...

An unpatched zero-day vulnerability dubbed StyleSmuggler affects all current versions of Magento and Adobe Commerce, including 2.4.9, enabling unauthenticated remote code execution. Active exploitation began on September 4th, 2026. The attack operates in two stages: injecting malicious PHP code into Magento's template system using styles properties to evade safeguards, then executing the poisoned code via failed payment emails. Upon successful compromise, attackers deploy a Rust-based backdoor disguised as legitimate system processes (kworker, fc-cache, or chronyd) that connects to command and control servers. The backdoor uses NTP-shaped UDP traffic for C2 communication to evade detection. A second unrelated attacker has also been observed exploiting the same vulnerability to deploy PHP web shells. Affected merchants should deploy immediate mitigation measures, scan for compromise, and temporarily disable GraphQL until an official patch is released.

Thirteen malicious Composer theme packages published on Packagist across five vendor namespaces inject JavaScript into Vietnamese movie and comic streaming sites. The injected code executes two operations: a mobile ad-fraud and gambling redirect chain, and on iPhones, a WebKit-to-kernel exploit chain installing spyware. The iOS chain weaponizes CVE-2025-31277 and CVE-2025-43529, targeting devices running iOS 18.4 through 18.6.x on iPhone XS through iPhone 16. The exploit chain progresses from WebKit renderer through GPU process to kernel escape via AppleM2ScalerCSCDriver, ultimately deploying spyware that exfiltrates keychain databases, cryptocurrency wallet seeds from seven wallet applications, Wi-Fi passwords, SMS, photos, contacts, and location data. Infrastructure resolves to FUNNULL, a sanctioned provider operated by Chinese national Liu Lizhi. The theme operators are Vietnamese-based, publishing trojanized forks of OphimCMS and KKPhim projects, affecting site operators who unknowingly serve malicious...

Analysis of 4 million dynamic malware reports reveals that 45.32% of malware samples with command-and-control activity establish direct-to-IP (D2IP) connections, bypassing DNS entirely and evading DNS-based security defenses. D2IP traffic accounts for 23.17% of all C2 connection attempts. This behavior is observed across diverse threats including Phorpiex ransomware droppers using hard-coded IP addresses, persistent data exfiltration campaigns employing obfuscated HTTP GET requests, SectopRAT targeting educational institutions with in-browser proxy capabilities, and IoT botnets like Mozi and Boatnet propagating through P2P networks. The research introduces zero trust IP (ZT-IP), a network-level enforcement approach that verifies whether outbound connection destinations were previously sanctioned by DNS responses, effectively blocking malicious D2IP communications that traditional DNS-based security controls cannot detect.

A fraudulent website impersonating Corepack, the Node.js package manager tool, is distributing malware to developers. The attackers exploit timing around Corepack's removal from Node.js bundling, targeting developers searching for installation instructions. The site offers Windows executables that deliver OpenShield infostealer and proxyware, enrolling victim machines in bandwidth-sharing networks without consent. The payload steals browser credentials, SSH keys, establishes persistence, and routes third-party traffic through compromised systems. An alternative download path delivers adware and trojan components disguised as OperaGX installer. The site features AI-generated content with obvious errors, including confusing Yarn package manager with textile crafts. The domain has been reported to registrars for takedown after community members identified the threat.

Cybercriminals are conducting phishing campaigns by hosting malicious pages on Vercel, a legitimate website hosting platform. The attack involves sending phishing emails with links to fake Adobe PDF viewer pages that prompt users to download executable files disguised as documents. The malware, distributed as Invoice06092025.exe.bin, automatically installs LogMeIn remote access software upon execution, enabling attackers to remotely control compromised machines. Over a two-month period, more than 28 distinct campaigns have been observed targeting over 1,271 users. The attackers leverage trusted platforms to disguise their malicious activity, making detection more challenging and increasing the likelihood of successful compromise.
