How to fix?

Upgrade php to version 8.1.30, 8.2.24, 8.3.12 or higher.

Overview

Affected versions of this package are vulnerable to Insufficient Granularity of Access Control due to the environment variable collision. An attacker can bypass the intended security restrictions by manipulating environment variables.

Note:

This is only exploitable if the server is configured to use cgi.force_redirect in a specific manner that does not properly isolate the PHP execution environment from external influences.
