NVD Description

Note: Versions mentioned in the description apply only to the upstream mod_proxy_html-debuginfo package and not the mod_proxy_html-debuginfo package as distributed by Amazon-Linux. See How to fix? for Amazon-Linux:2023 relevant fixed versions and status.

SSRF in Apache HTTP Server with mod_proxy loaded allows an attacker to send outbound proxy requests to a URL controlled by the attacker.  Requires an unlikely configuration where mod_headers is configured to modify the Content-Type request or response header with a value provided in the HTTP request.

Users are recommended to upgrade to version 2.4.64 which fixes this issue.
