CVE-2025-5469

Local code execution via uncontrolled dylib search

Published Dec 9, 2025 · Updated Dec 9, 2025

Uncontrolled search path handling in Yandex Messenger before 2.245 allows local users to execute code through dylib hijacking. Yandex identifies the macOS desktop application's dynamic-library search order as uncontrolled but has not disclosed the library, path element, or load operation involved. Exploitation requires low-privileged local access and an unspecified additional condition, after which attacker-supplied code runs in the application's context.
