### Description CVE-2024-50340 (GHSA-x8vp-gf4q-mw5j) addressed an issue where, with `register_argc_argv=On`, a crafted query string let an unauthenticated GET change the kernel environment and debug flag by feeding `--env`/`--no-debug` through `$_SERVER['argv']`. The fix shipped in `symfony/runtime` 5.4.46 / 6.4.14 / 7.1.7 gated the argv read on `empty($_GET)` as a proxy for "is this a CLI invocation". That proxy is unsafe: `parse_str()` (which builds `$_GET`) and the web SAPI (which builds `$_SERVER['argv']` from the raw query when `register_argc_argv=On`) do not agree on every input, so an attacker can craft a query that leaves `$_GET` empty while `$_SERVER['argv']` carries the attacker's flags. `SymfonyRuntime::getInput()` then parses them, restoring the exact primitive CVE-2024-50340 was meant to prevent. Preconditions and impact match the original CVE: web SAPI, `register_argc_argv=On`, app booted through `symfony/runtime`; from an unauthenticated GET an attacker can flip `APP_ENV` and toggle `APP_DEBUG`. ### Resolution `SymfonyRuntime` now gates the argv read on `isset($_SERVER['QUERY_STRING'])` rather than on `empty($_GET)`. `QUERY_STRING` is the same input the SAPI use

A fixed release is not deployment evidence.

Check current vendor support and compatibility. After making a change, verify the deployed build and relevant runtime conditions. Keep the evidence, owner and time. An updated lockfile alone does not prove what is running.
