CVE-2026-40604

ClearanceKit intercepts file-system access events on macOS and enforces per-process access policies. Prior to 5.0.6, the opfilter Endpoint Security system extension (bundle ID uk.craigbass.clearancekit.opfilter) can be suspended with SIGSTOP or kill -STOP, or killed with SIGKILL/SIGTERM, by any process running as root. While the extension is suspended, all AUTH Endpoint Security events time out and default to allow, silently disabling ClearanceKit's file-access policy enforcement for the duration of the suspension. This vulnerability is fixed in 5.0.6.

Summary		(es) ClearanceKit intercepta eventos de acceso al sistema de archivos en macOS y aplica políticas de acceso por proceso. Antes de 5.0.6, la extensión de sistema de seguridad de punto final opfilter (ID de paquete uk.craigbass.clearancekit.opfilter) puede ser suspendida con SIGSTOP o kill -STOP, o terminada con SIGKILL/SIGTERM, por cualquier proceso que se ejecute como root. Mientras la extensión está suspendida, todos los eventos AUTH de seguridad de punto final agotan el tiempo de espera y por defecto permiten, deshabilitando silenciosamente la aplicación de políticas de acceso a archivos de ClearanceKit durante la duración de la suspensión. Esta vulnerabilidad se corrige en 5.0.6.
