# Security digest: October 26, 2026

2 known exploited (cisa kev) additions.

## Take stock

- Do you run any of these? PHP Group PHP. They are being exploited in the wild (CISA KEV). Patch or mitigate if you do; CISA’s federal deadline is 2026-10-29.
- None of it touches your stack? Then there is nothing to do today. That is a result, not a failure to read carefully.
