Here is everything you need to know about this update. Please take a good look at what changed and the test results before merging this pull request.
Clients could clobber values set by intermediate proxies (such as X-Forwarded-For) by providing a underscore version of the same header (X-Forwarded_For). Any users trusting headers set by their proxy may be affected. Attackers may be able to downgrade connections to HTTP (non-SSL) or redirect responses, which could cause confidentiality leaks if combined with a separate MITM attack.
Patches
v6.4.3/v5.6.9 now discards any headers using underscores if the non-underscore version also exists. Effectively, allowing the proxy defined headers to always win.
Workarounds
Nginx has a underscores_in_headers configuration variable to discard these headers at the proxy level.
Any users that are implicitly trusting the proxy defined headers for security or availability should immediately cease doing so until upgraded to the fixed versions.
Discards any headers using underscores if the non-underscore version also exists. Without this, an attacker could overwrite values set by intermediate proxies (e.g. X-Forwarded-For). (CVE-2024-45614/GHSA-9hf4-67fc-4vf4)
