CVE-2025-43013

Credential disclosure via cleartext SSH authentication

Published Apr 17, 2025 · Updated Apr 17, 2025

Cleartext credential transmission in JetBrains Toolbox App before 2.6 allows attackers to obtain SSH authentication credentials. JetBrains has not published the affected function or transport path, beyond stating that the SSH authentication flow sent credentials without encryption. The CNA vector requires local high-privileged access and user interaction; exploitation exposes credentials and has limited integrity and availability effects.
