Details

pgjdbc Client Allows Fallback to Insecure Authentication Despite channelBinding=require Configuration ### Impact When the PostgreSQL JDBC driver is configured with channel binding set to `required` (default value is `prefer`), the driver would incorrectly allow connections to proceed with authentication methods that do not support channel binding (such as password, MD5, GSS, or SSPI authentication). This could allow a man-in-the-middle attacker to intercept connections that users believed were protected by channel binding requirements. ### Patches TBD ### Workarounds Configure `sslMode=verify-full` to prevent MITM attacks. ### References * https://www.postgresql.org/docs/current/sasl-authentication.html#SASL-SCRAM-SHA-256 * https://datatracker.ietf.org/doc/html/rfc7677 * https://datatracker.ietf.org/doc/html/rfc5802
