CVE-2025-13524Network attack vector

Audio disclosure via unterminated call stream

Published Nov 21, 2025 · Updated Nov 21, 2025

Improper resource release in AWS Wickr desktop before 6.62.13 allows remote authenticated users to keep receiving another user's audio. The call termination process closes the affected user's call window without terminating that user's outgoing audio stream, leaving it open to other participants. The behavior affects Wickr, Wickr Gov, and Wickr Enterprise desktop clients on Windows, macOS, and Linux; it requires a particular in-app action by the affected user and ends when other participants leave, the affected user joins another call, or the application terminates.
