CVE-2026-13067

When PROXY protocol v2 is used on the Unix domain socket path, roles derived from X.509 client certificates may not be validated against the configured tlsCATrusts allow-list. This can result in unintended role assignments following MONGODB-X509 authentication. Affected scenarios require local access to the proxy Unix domain socket and a valid X.509 certificate issued by a trusted certificate authority.

Summary		(es) Cuando se utiliza el PROXY protocol v2 en la ruta del socket de dominio Unix, los roles derivados de los certificados de cliente X.509 pueden no ser validados contra la lista de permitidos tlsCATrusts configurada. Esto puede resultar en asignaciones de roles no intencionadas después de la autenticación MONGODB-X509. Los escenarios afectados requieren acceso local al socket de dominio Unix del proxy y un certificado X.509 válido emitido por una autoridad de certificación de confianza.
