Description Vladimir Vasilev 2026-10-02 11:20:19 UTC

Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

Missing authentication checks in mod_auth_digest in Apache Software Foundation Apache HTTP Server before 2.4.69 on all platforms allows an unauthenticated remote client to cause a denial of service (forced re-authentication) via forged Authorization headers when Digest authentication is enabled with AuthDigestNcCheck .

Users are recommended to upgrade to version 2.4.69, which fixes this issue.
