Doc Text:
A connection handling flaw was found in the pgjdbc connection driver in configurations that require channel binding. Connections created with authentication methods that should not allow channel binding permit connections to use channel binding. This flaw allows attackers to position themselves in the middle of a connection and intercept the connection.

Description OSIDB Bzimport 2025-06-11 15:01:57 UTC 
pgjdbc is an open source postgresql JDBC Driver. From 42.7.4 and until 42.7.7, 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. This vulnerability is fixed in 42.7.7.
