PHP Windows packages patched for Brotli RCE flaw CVE-2026-111497
- Engineer — Act: EPSS 0.55 plus a public GitHub PoC make this Act: update Windows PHP packages to the latest 8.2–8.5 builds immediately, and audit any application that enables cURL’s CURLOPT_ENCODING (automatic Brotli decompression), since that is the exploitable path.
- SOC/IR — Plan: No active exploitation or KEV listing yet, but a public PoC and high EPSS warrant building a detection for anomalous PHP-CGI/FastCGI process behavior on Windows hosts; queue a hunt for known PoC signatures once they stabilize.
- Leader — Skip
- Signals: CVE-2026-111497 — CISA KEV: not listed, EPSS 0.55, public PoC on GitHub
