DEBIAN-CVE-2026-47767
Symfony is a PHP framework for web and console applications and a set of reusable PHP components. From 5.4.46 until 5.4.52, 6.4.40, 7.4.12, and 8.0.12, the CVE-2024-50340 fix gated runtime argv parsing on empty($GET), but parsestr() and the web SAPI can disagree, allowing a crafted query string to leave $GET empty while $SERVER['argv'] still carries attacker-controlled --env or --no-debug flags that change APPENV or APPDEBUG. This issue is fixed in versions 5.4.52, 6.4.40, 7.4.12, and 8.0.12.
