Vulnerability in org.http4k:http4k-security-digest (CVE-2026-54148)
Summary
Vulnerability in org.http4k:http4k-security-digest (CVE-2026-54148). Confidential information can be exposed externally. Exploitable via DigestAuthProvider.verify. Mitigation: upgrade to 4.51.0.0 or later.
Original description
The description as published by the source.
Impact
An issue in DigestAuthProvider.verify:
The uri parameter in the client's Authorization: Digest … 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.
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).
Patches
| Line | Fixed in | Edition |
|---|---|---|
| v6.x (Community) | 6.50.0.0 | Community |
| v5.x (LTS) | 5.42.0.0 | Enterprise — contact enterprise@http4k.org (if Digest auth is present in your v5.x line) |
| v4.x (LTS) | 4.51.0.0 | Enterprise — contact enterprise@http4k.org (if Digest auth is present in your v4.x line) |
The fix:
- Rejects credentials whose
uriparameter does not match the request URL.
Workarounds
For deployments that cannot upgrade immediately:
- URI binding gap: place Digest auth behind a reverse proxy that pins requests to a single URL.
