HIGHPre-NVD 8.18.1
EchelonGraph scoreLOW confidence

This high-severity CVE scores 8.1 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit-prediction score not yet available (the EPSS model rescores nightly; freshly-published CVEs typically appear within 48 hours). GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

http4k is a functional toolkit for Kotlin HTTP applications. 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. This issue is fixed in versions 4.51.0.0, 5.42.0.0, and 6.50.0.0.
