From 5c661a48054d97f7835edaf3f5bfff30a73d9b9c Mon Sep 17 00:00:00 2001 From: Chris Date: Wed, 21 Oct 2026 17:43:59 +0200 Subject: [PATCH] Mitigate PHP RCE advisories GHSA-6wmf-4rv5-p3rp / GHSA-w8hw-w9fx-j79w Stopgap for the PHP RCE advisories GHSA-6wmf-4rv5-p3rp and GHSA-w8hw-w9fx-j79w (2026-10-21): disable session.upload_progress (and fatal_error_backtraces on PHP 8.5). Upload progress should stay off even after patched PHP is deployed. Bump the EOL Alpine base to 3.24 so php83 receives the 8.3.36 security release. Alpine 3.24 no longer ships /usr/bin/php for php83, so add the link.
