GHSA-hq9p-pm7w-8p54: org.postgresql:postgresql (CVE-2025-49146)

Package	Ecosystem	Affected	Fixed in
org.postgresql:postgresql	Maven	>=42.7.4, <42.7.7	42.7.7

Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

The org.postgresql:postgresql package versions 42.7.4 up to but not including 42.7.7 is affected. When channelBinding is set to require, the driver still allows authentication methods that cannot use channel binding, such as password, MD5, GSS or SSPI. A man-in-the-middle attacker positioned on the network path could intercept connections that users believed were protected. Upgrade to version 42.7.7. As a workaround, set sslMode to verify-full.
