PHP2Shell, the pair of critical PHP flaws, is now being exploited at scale, and Amazon says probing began four days before the patches; government sites in Australia, the UK and Europe went offline as a precaution. GitLab fixed a maximum-severity flaw reaching back to 2014, and Microsoft tied the ConnectWise cloud compromise to China-aligned Storm-0940 using ARTEX AI agents. LiteLLM traced its poisoned release to GitHub tokens captured in its own AI gateway logs.

Outlook and patch priorities
- Critical (today): finish PHP patching (8.5.12, 8.4.27, 8.3.36, 8.2.35), restart workers, assess internet-facing PHP hosts from 17 October; restrict internet-facing PAN-OS management interfaces; upgrade self-managed GitLab.
