CVE-2020-11470Public exploit

Camera and microphone access via library injection

Published Apr 1, 2020 · Updated Aug 4, 2024

Code injection in Zoom Client for Meetings 4.6.8 and earlier allows local users to access the camera and microphone without prompts. The macOS app carries the disable-library-validation entitlement, so dyld accepts a crafted proxy library from its bundle and runs that code inside Zoom's permission-bearing process. Exploitation requires a local foothold and yields device access only when Zoom already has camera or microphone permission.
