Summary

http4k: `DigestAuthProvider.verify` did not bind to request URI

Details

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 uri parameter 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.

CVE-2026-54148 (GCVE-0-2026-54148)

Vulnerability from cvelistv5 – Published: 2026-09-18 16:09 – Updated: 2026-09-22 14:54

Title

http4k: `DigestAuthProvider.verify` did not bind to request URI

Summary

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.

Severity
