Restricted-file disclosure via SoftwareUpdate entitlement flaw
Published May 26, 2022 · Updated Aug 3, 2024
Information disclosure in Apple SoftwareUpdate on affected macOS releases allows local users to read restricted files through a malicious app. The helper places personalized manifests sourced from a TCC-protected location under a broadly readable SoftwareUpdate path because its entitlements are overly permissive. Exploitation requires a user to run the malicious application; the demonstrated consequence is disclosure of TCC-protected local files.
