Bot-protection bypass via trusted client header
Published Jul 15, 2026 · Updated Jul 15, 2026
Improper access control in Techaro Anubis 1.22.0 through 1.25.0 allows remote attackers to bypass bot challenges via an HTTP header. PathChecker.Check() in lib/policy/checker.go evaluates the client-supplied X-Original-URI as a trusted path before r.URL.Path, so it can satisfy an ALLOW regex. The default policy's path-only rules make the bypass unauthenticated and expose upstream content without a challenge or JWT check.
