Prior to 4.51.0.0, 5.42.0.0, and 6.50.0.0, DigestAuthProvider.verify in http4k-security-digest does not compare the uri parameter in an Authorization: Digest response with the actual request URL. An attacker who captures a valid Digest authentication response can replay it against another URL served by the same realm, bypassing the per-request-URI binding and potentially gaining unauthorized read or write access.
