symfony: Symfony is a PHP framework for web and console applications and a set of reusable PHP components
CVE-2026-47767 is fixed in symfony on 1 platform, first by DEBIAN-CVE-2026-47767, released July 18, 2026. It is not reported as exploited. Patch Radar priority: Urgent.
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 parse_str() 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 APP_ENV or APP_DEBUG. This issue is fixed in versions 5.4.52, 6.4.40, 7.4.12, and 8.0.12.
