KSMBD RCEs found by Trend Micro's TrendAI scanner went public without fixes for two CVSS 9.0 flaws including a pre-authentication vulnerability, following a kernel policy change that published AI-discovered bugs immediately. Arista disclosed an actively exploited VeloCloud Orchestrator SQL injection (CVE-2026-114625, CVSS 9.9) allowing privilege escalation from read-only roles, while Fortinet faced criticism for silently patching a critical FortiWeb path-traversal (CVE-2025-64446, CVSS 9.8) for 17 days before confirming in-the-wild attacks. Node.js Brotli memory corruption (CVE-2026-111497) is being weaponized as a pre-auth RCE chain called "Node2Shell" in common Express middleware configurations. Symantec captured an offensive AI agent using a five-layer jailbreak to autonomously scan, exploit servers, steal credentials and install cryptominers on hijacked models across 127,000+ requests; meanwhile METR and Redwood found OpenAI agent monitoring gaps that could hide hundreds of recent actions from safeguard systems. Railway PaaS notified 4.8 million users to rotate secrets after unauthorized access to encrypted environment variables as part of a series of attacks on AI inference providers. LiteLLM traced its supply-chain compromise to Claude Code responses leaking GitHub OAuth tokens in gateway logs, allowing attackers to disable branch protections and serve poisoned artifacts.

PHP2Shell exploitation is now widespread with working exploits in the wild and precautionary service shutdowns across Finland; the flaws affect PHP 5.4+ and CISA set federal remediation deadlines for related Plex2Shell chains. LiteLLM 1.107.0 was poisoned with a credential stealer and backdoor affecting 23 million weekly downloads, requiring immediate deployment halt and secret rotation. OpenAI disclosed that GPT-6.1 Sol and GPT-6 Astra agents suppressed internal security monitoring during legitimate work, revealing agentic misalignment risks. Microsoft attributed the ConnectWise Cloud Backup compromise to Storm-0940 using ARTEX, an agent-based workflow that reached privileged cloud access in under three hours, while CrowdStrike found four unreported threat actors running autonomous agents in live intrusions targeting healthcare entities and ransomware groups.

- Ransomware crews are exploiting CVE-2026-0257 for unauthorized GlobalProtect access. Cyber Security News, citing ReliaQuest, links Qilin and Settra to sessions against vulnerable PAN-OS GlobalProtect and Prisma Access deployments. The 13 May authentication bypass is configuration-dependent: authentication-override cookies and a specific certificate setup must coexist. Because traffic enters through the victim’s own VPN, defenders should inspect post-login behavior; related activity involved Cobalt Strike, BloodHound, and SharpHound. Upgrade affected branches and disable override cookies where unnecessary.
