28
FAUCET Score

CVE-2022-48195 affects Mellium's mellium.im/sasl library prior to version 0.3.1, specifically impacting SCRAM-based SASL authentication. The vulnerability arises when channel binding is advertised, causing an empty nonce to be used instead of a random one. This critical flaw (CVSS 9.8) allows for potential authentication bypass or insufficient randomness, leading to high confidentiality, integrity, and availability impacts, with no user interaction required. Currently, there is no evidence of active exploitation, public exploit code, or significant community discussion surrounding this vulnerability.
