Name of the Vulnerable Software and Affected Versions Zoom Client for Meetings versions 4.6.8 and earlier

Description The issue allows a local process to obtain unprompted microphone and camera access by loading a crafted library, thereby inheriting the Zoom Client's access. This is possible due to the disable-library-validation entitlement.

Recommendations For Zoom Client for Meetings versions 4.6.8 and earlier, consider updating to a version that does not have the disable-library-validation entitlement to prevent local processes from obtaining unprompted microphone and camera access. As a temporary workaround, consider restricting access to the microphone and camera for the Zoom Client to minimize the risk of exploitation.
