CVE-2025-43252Network attack vector

Sensitive-data disclosure via unprompted symlink resolution

Published Jul 29, 2025 · Updated Apr 2, 2026

Link-following in the zip component in Apple macOS before 15.6 allows remote attackers to read sensitive user data through a website. The zip component resolves symbolic links to protected files without obtaining the additional user consent required for that access. Exploitation requires a user to interact with attacker-controlled web content; the documented impact is disclosure of local data, not modification or service interruption.
