What is CVE-2026-48005?

An issue exists in the mod_auth_digest module of Apache HTTP Server, where missing authentication checks enable unauthenticated remote clients to initiate forced re-authentication. This could lead to a denial of service, especially when Digest authentication is enabled with the AuthDigestNcCheck directive. It is crucial for users to upgrade to version 2.4.69 or later to mitigate this vulnerability and secure their web servers from potential exploitation.

Affected Version(s)
