CVE-2023-33982 (GCVE-0-2023-33982)
Vulnerability from nvd – Published: 2023-05-24 00:00 – Updated: 2025-01-16 15:48
VLAI
Summary
Bramble Handshake Protocol (BHP) in Briar before 1.5.3 is not forward secure: eavesdroppers can decrypt network traffic between two accounts if they later compromise both accounts. NOTE: the eavesdropping is typically impractical because BHP runs over an encrypted session that uses the Tor hidden service protocol.

CVE-2023-33982 (GCVE-0-2023-33982)
Vulnerability from cvelistv5 – Published: 2023-05-24 00:00 – Updated: 2025-01-16 15:48
VLAI
Summary
Bramble Handshake Protocol (BHP) in Briar before 1.5.3 is not forward secure: eavesdroppers can decrypt network traffic between two accounts if they later compromise both accounts. NOTE: the eavesdropping is typically impractical because BHP runs over an encrypted session that uses the Tor hidden service protocol.
Severity
