A vulnerability was found in mod_wsgi. The X-Client-IP header is not removed from a request from an untrusted proxy, allowing an attacker to pass the X-Client-IP header to the target WSGI application because the condition to remove it is missing.

It is, therefore, affected by a vulnerability as referenced in the ALAS2HTTPD_MODULES-2023-001 advisory.
