[php-src] Issue #11464: FPM: Consider escaping script in status

Issue: https://github.com/php/php-src/issues/11464 Author: bukka ### Description Currently the script field in status is not escaped for neither JSON, HTML nor XML. It should be investigated if any of the characters requiring escape can get to the script filename. This is very unlikely issue in practice but potentially theoretical possible so it might be a good idea to address it. The thing to try would be to have a script whose path needs to be escaped. The server might be able to access with URL escape that is eventually transformed to the path with a character requiring an escape. This needs some testing if it's even possible. ### PHP Version Any with FPM ### Operating System Linux
