CVE-2025-43233

Sensitive data disclosure via malicious HTTPS proxy

Published Jul 29, 2025 · Updated Apr 2, 2026

Improper access control in Apple macOS before 13.7.7, 14.7.7, and 15.6 allows local users to read sensitive data via an HTTPS proxy app. The Security component applies inadequate access restrictions when a malicious app acts as an HTTPS proxy, but Apple has not disclosed the specific code locus or protected data involved. Exploitation requires local execution of the proxy app; the documented consequence is sensitive-data disclosure, with no stated integrity or availability impact.
