✓ GitHub Reviewed

Has CVE
Advisory Details
### Description
When the `register_argc_argv` 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.
### Resolution
The `SymfonyRuntime` now ignores the `argv` values for non-cli SAPIs PHP runtimes
The patch for this issue is available [here](https://github.com/symfony/symfony/commit/a77b308c3f179ed7c8a8bc295f82b2d6ee3493fa) for branch 5.4.
