  "description": "The mod_wsgi adapter is an Apache module that provides a WSGI compliant interface for hosting Python based web applications within Apache. The adapter is written completely in C code against the Apache C runtime andfor hosting WSGI applications within Apache has a lower overhead than using existing WSGI adapters for mod_python or CGI.\r\n\r\nSecurity Fix(es):\r\n\r\nA vulnerability was found in mod_wsgi. The X-Client-IP header is not removed from a request from an untrusted proxy (trusted proxies are configured via the WSGITrustedProxies directive) allowing an attacker to pass the X-Client-IP header to the target WSGI application because the condition to remove it is missing.\r\n\r\nReferences:\nhttps://github.com/GrahamDumpleton/mod_wsgi/blob/4.9.2/src/server/mod_wsgi.c#L13940-L13941\nhttps://github.com/GrahamDumpleton/mod_wsgi/blob/4.9.2/src/server/mod_wsgi.c#L14046-L14082(CVE-2022-2255)",
