SCA: security update for org.postgresql:postgresql (GHSA-98qh-xjc8-98pq)

high Tenable Self-Hosted Container Security Plugin ID 441233

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - pgjdbc is an open source postgresql JDBC Driver. From version 42.2.0 to before version 42.7.11, pgjdbc is
 vulnerable to a client-side denial of service during SCRAM-SHA-256 authentication. A malicious server can
 instruct the driver to perform SCRAM authentication with a very large iteration count. With a large enough
 value, the client spends an unbounded amount of CPU time inside PBKDF2 before authentication can fail. A
 single attempt ties up a CPU core. Repeated or concurrent attempts exhaust client CPU and can wedge
 connection pools. In affected versions, loginTimeout did not fully mitigate this problem. When
 loginTimeout expired, the caller could stop waiting, but the worker thread performing the connection
 attempt could continue running and burning CPU inside the SCRAM PBKDF2 computation. This issue has been
 patched in version 42.7.11. (CVE-2026-42198)

Solution

Update the org.postgresql:postgresql library and its related packages to version 42.7.11 or later.
