CVE-2026-109575 is a critical authentication bypass vulnerability in HAProxy Data Plane API Enterprise Edition versions 2.2.0 through 3.4.3. The flaw occurs because the global authentication logic disables Basic authentication on shared internal request handlers when TLS CA and numeric TLS port are configured, but mutual TLS verification is only enforced on the HTTPS path. This allows unauthenticated attackers to access HTTP or UNIX domain socket management endpoints without credentials, gaining full administrative API access. The vulnerability enables reading or replacing HAProxy configuration remotely or locally. It is fixed in versions 3.4.4, 3.3.9, 3.2.17, 3.0.25, 2.9.29, and corresponding Enterprise Edition backports.
