Name of the Vulnerable Software and Affected Versions: Wire for iOS versions prior to 3.75

Description: The issue is a privacy concern where video capture isn't stopped when a user disables their camera during a video call, causing video to be streamed to the call even when the user believes it is disabled. This affects all users in video calls.

Recommendations: For versions prior to 3.75, update to version 3.75 to resolve the issue. As a temporary workaround, consider disabling video calls until the update is applied.
