The helper authorizes connecting XPC clients by comparing the caller's code-signing certificate chain for equality with its own, rather than validating the caller against a pinned code requirement (application identifier and Team ID). A local, authenticated user can execute code within the vendor-signed process, satisfy the helper's client check, and cause the helper to execute a script with root privileges. Fixed in 17.0.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"twilight","depthScore":39,"depthScoreParts":{"impact":39.1,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
