PostgreSQL JDBC library -- Improper Authentication

PostgreSQL JDBC Driver project reports: Client Allows Fallback to Insecure Authentication Despite channelBinding=require configuration. Fix channel binding required handling to reject non-SASL authentication Previously, when channel binding was set to "require", the driver would silently ignore...

CVE-2025-49146

A connection handling flaw was found in the pgjdbc connection driver in configurations that require channel binding.

CVE-2025-49146

CVE-2025-49146 affects the PostgreSQL JDBC driver (pgjdbc). From 42.7.4 through 42.7.7, when channel binding is set to required, connections could proceed using non-SASL authentication methods (e.g., password, MD5, GSS, SSPI), enabling MITM interception. The issue is fixed in 42.7.7. Affected con...

GO-2023-1268 Authentication failure in mellium.im/sasl

An issue was discovered in Mellium mellium.im/sasl before 0.3.1. When performing SCRAM-based SASL authentication, if the remote end advertises support for channel binding, no random nonce is generated instead, the nonce is empty. This causes authentication to fail in the best case, but if paired...
