Remote code execution via malformed URL parsing
Published Dec 15, 2022 · Updated Apr 21, 2025
Improper URL validation in the iTunes Store component of macOS Ventura before 13.1 and watchOS before 9.2 allows remote attackers to execute code. The URL parser does not adequately validate a URL before parsing it, although Apple has not disclosed the affected routine or malformed URL structure. No authentication or user interaction is required; processing a malicious URL can crash the affected app or execute code in its security context.
