CVE-2024-50340

Ability to change environment from query in symfony/runtime

7.3 HighPublic exploitFix available

symfony/runtime is a module for the Symphony PHP framework which enables decoupling PHP applications from global state. When the register_argv_argc php directive is set to on , and users call any URL with a special crafted query string, they are able to change the environment or debug mode used by the kernel when handling the request. As of versions 5.4.46, 6.4.14, and 7.1.7 the SymfonyRuntime now ignores the argv values for non-SAPI PHP runtimes. All users are advised to upgrade. There are no known workarounds for this vulnerability.
