  "details": "### Impact\n\nAn issue in `DigestAuthProvider.verify`:\n\nThe `uri` parameter in the client\u0027s `Authorization: Digest \u2026` response was not checked against the actual request URL. A captured Digest authentication response could be replayed against any other URL served by the same realm, breaking the per-request-URL binding the Digest scheme assumes.\n\n**Who is affected:** any application using `http4k-security-digest` for HTTP Digest authentication. The bug has been present since `DigestAuthProvider` was introduced (commit `8a52b615b1`, 2021).\n\n### Patches\n\n| Line | Fixed in | Edition |\n|------|----------|---------|\n| v6.x (Community) | **6.50.0.0** | Community |\n| v5.x (LTS) | **5.42.0.0** | Enterprise \u2014 contact [enterprise@http4k.org](mailto:enterprise@http4k.org) (if Digest auth is present in your v5.x line) |\n| v4.x (LTS) | **4.51.0.0** | Enterprise \u2014 contact [enterprise@http4k.org](mailto:enterprise@http4k.org) (if Digest auth is present in your v4.x line) |\n\nThe fix:\n- Rejects credentials whose `uri` parameter does not match the request URL.\n\n### Workarounds\n\nFor deployments that cannot upgrade immediately:\n- **URI binding gap:** place Digest auth behind a reverse proxy that pins requests to a single URL.\n\n### References\n\n- Vulnerability first present: [`8a52b615b1`](https://github.com/http4k/http4k/commit/8a52b615b1)\n- URI binding fix: [`725f1b9697`](https://github.com/http4k/http4k/commit/725f1b9697)\n- Fix release: [v6.50.0.0](https://github.com/http4k/http4k/releases/tag/6.50.0.0)\n- Background: [RFC 7616 \u2014 HTTP Digest Access Authentication](https://datatracker.ietf.org/doc/html/rfc7616)",
