Improper certificate validation and a time-of-check time-of-use (TOCTOU) race condition in the PrivilegedHelperTool XPC service in Cato Client before v.5.13.1 on macOS allows a local authenticated attacker to escalate privileges to root via a self-signed certificate that bypasses the XPC caller verification and a symlink swap during package installation.
