GHSA-7R4P-VJF4-GXV4 Caddy forward_auth copy_headers Does Not Strip Client-Supplied Headers, Allowing Identity Injection and Privilege Escalation

Summary Caddy's forwardauth directive with copyheaders generates conditional header-set operations that only fire when the upstream auth service includes the named header in its response. No delete or remove operation is generated for the original client-supplied request header with the same name...
