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.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n## Package advisory (CVE-2026-54148)\n\nAffected packages:\n\n- `org.http4k:http4k-security-digest >= 6.0.0.0, < 6.50.0.0`\n- `org.http4k:http4k-security-digest >= 5.0.0.0, < 5.42.0.0`\n- `org.http4k:http4k-security-digest <= 4.48.2.0`\n\nPatched in:\n\n- `org.http4k:http4k-security-digest 6.50.0.0`\n- `org.http4k:http4k-security-digest 5.42.0.0`\n\nSource: https://github.com/advisories/GHSA-p28p-j94q-pg32","depth":"twilight","depthScore":45,"depthScoreParts":{"impact":44.6,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
