GitHub Vulnerability Alerts

CVE-2025-49146

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.

Release Notes

pgjdbc/pgjdbc (org.postgresql:postgresql)

v42.7.7

Security

• security: 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 this
  requirement for non-SASL authentication methods. This could lead to a false sense of security
  when channel binding was explicitly requested but not actually enforced. The fix ensures that when
  channel binding is set to "require", the driver will reject connections that use
  non-SASL authentication methods or when SASL authentication has not completed properly.
  See the Security Advisory for more detail. Reported by George MacKerron
  The following CVE-2025-49146 has been issued

Added

• test: Added ChannelBindingRequiredTest to verify proper behavior of channel binding settings
