CVE-2026-120317

Medium

Description

http4k from 4.9.10.0 before 6.60.0.0 contains a missing integrity check vulnerability because DigestEncoder computes the auth-int digest without hashing the request entity body. On-path attackers on non-TLS channels can rewrite the body of authenticated requests while keeping the Authorization header valid, executing state-changing actions as the victim.
