http4k: `DigestAuthProvider.verify` ignored configured algorithm and did not bind to request URI
Impact
An issue in DigestAuthProvider.verify:
Algorithm silently forced to MD5. The configured algorithm parameter was ignored — every verification used MD5 regardless of configuration. Deployments believing they were running SHA-256 Digest auth were silently inheriting MD5's collision weaknesses, including documented attack paths against Digest schemes that rely on the hash being collision-resistant.
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:
- Hashes with the configured
algorithminstead of hardcoded MD5.
Workarounds
For deployments that cannot upgrade immediately:
- Algorithm gap: do not rely on
algorithmconfiguration; assume MD5 is in use and treat the Digest credentials as low-trust.
