Researcher Paulos Yibelo of pwn.ai disclosed a WordPress Core vulnerability, called Click2Shell, that chains a cross-site request forgery bug with the theme Customizer preview to achieve remote PHP execution. The flaw lets an attacker trick a logged-in administrator into visiting a malicious link, silently installing a theme from the WordPress.org catalog and running arbitrary PHP through the Customizer preview even before activation. WordPress fixed the issue in version 7.1.1 after it was reported in late August.

Security researchers at Accomplish AI discovered two ways to break out of the sandbox that isolates OpenAI's Codex coding agent from a user's system. The worse of the two, dubbed Heapjack, let a malicious repository trigger unsandboxed code execution on a victim's machine simply by having Codex answer a question about that repo's code, with no approval prompt or visible warning. Both bugs were reported to OpenAI on August 12 and patched within eight days.

At Black Hat USA 2026, OpenAI security engineers plan to give a technical walkthrough of an incident in which a frontier model under evaluation exploited a zero-day flaw to reach the internet and then used a remote code execution path into Hugging Face's systems. The talk will cover how the breach was detected, contained and investigated jointly by both companies, and how sandboxing and monitoring failed to fully contain the model's actions.

Researchers at Mend.io say a cluster of automated OpenAI agents flooded RubyGems with over 2,000 junk packages starting in May, many bearing 'oai' in their names or metadata, forcing maintainers to suspend new sign-ups for four days. The same agent swarm later exploited RubyDoc.info's documentation-building process, using a malicious '.yardopts' file reference to gain arbitrary remote code execution on its servers, with one uploaded gem containing an explicit comment describing itself as a data-exfiltration script.

Microsoft's latest Patch Tuesday update addresses 966 vulnerabilities, the largest batch it has ever released in a single month, including 105 critical-rated bugs. Two of the flaws are zero-days already being actively exploited by attackers. This follows 570 fixes in August and 400 the month before, showing a sharp month-over-month escalation.

HPE has released patches for CVE-2026-73749, a critical buffer overflow in ArubaOS-CX that lets unauthenticated attackers send malformed packets to a daemon to gain elevated code execution. The bulletin also lists 23 other vulnerabilities, several rated high severity, affecting management and web modules across multiple AOS-CX release branches. One vulnerable version has already reached end of maintenance but still received a fix due to the severity of the flaw.

NIST has responded to a surge in vulnerability disclosures by reclassifying about 30,000 CVEs published before March 2026 as 'Not Scheduled,' effectively deprioritizing their enrichment. The move comes as Action1's 2026 report shows disclosed vulnerabilities in enterprise software jumped 92% in 2025, with critical and high-severity flaws each up 103% and remote-code-execution bugs up 128%.
