The PostgreSQL JDBC team have released version 42.7.7. to address [CVE-2025-49146](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2025-49146)
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.
See the [security advisory](https://github.com/pgjdbc/pgjdbc/security/advisories/GHSA-hq9p-pm7w-8p54) for details
Thanks to [George MacKerron](https://github.com/jawj) for finding and reporting the issue.
