Subject: CVE-2026-48005: Apache HTTP Server: mod_auth_digest
 reauthentication attack 

Severity: low 

Affected versions:

- Apache HTTP Server 2.4.0 through 2.4.68

Description:

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 .
