CVE-2026-40599

ClearanceKit intercepts file-system access events on macOS and enforces per-process access policies. Prior to 5.0.5, ClearanceKit incorrectly treats a process with an empty Team ID and a non-empty Signing ID as an Apple platform binary. This bug allows a malicious software to impersonate an apple process in the global allowlist, and access all protected files. This vulnerability is fixed in 5.0.5.

Summary		(es) ClearanceKit intercepta eventos de acceso al sistema de archivos en macOS y aplica políticas de acceso por proceso. Antes de la versión 5.0.5, ClearanceKit trata incorrectamente un proceso con un Team ID vacío y un Signing ID no vacío como un binario de plataforma de Apple. Este error permite que un software malicioso suplante un proceso de Apple en la lista de permitidos global y acceda a todos los archivos protegidos. Esta vulnerabilidad está corregida en la versión 5.0.5.
