Low signal — verdict needed

Few public signals point to active risk. Whether a scanner hit here is a true or false positive depends on your version and config — community verdicts decide.

A weakness has been identified in DeepMyst Mysti 0.4.0. Affected is the function _isTrackedConversation of the file src/managers/ChannelBridge.ts of the component Contact Tracking.
