Vulnerability from github – Published: 2022-11-13 12:00 – Updated: 2022-11-17 18:30

Details

SimpleXMQ before 3.4.0, as used in SimpleX Chat before 4.2, does not apply a key derivation function to intended data, which can interfere with forward secrecy and can have other impacts if there is a compromise of a single private key. This occurs in the X3DH key exchange for the double ratchet protocol.

Severity

5.3 (Medium)
