Echo: pgbouncer: security update to 1.26.0-1

high Tenable Self-Hosted Container Security Plugin ID 455317

Description

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

 - Missing validation of a mandatory attribute in the SCRAM client-final-message parser in PgBouncer through
 1.25.2 allows an unauthenticated remote attacker to crash the process. A malformed message can make the
 parser report success while leaving a required value unset, which is then dereferenced as a NULL pointer.
 The crash occurs before any credential is verified, so no valid account is required. Because PgBouncer
 serves all clients from a single process, this terminates every pooled connection. (CVE-2026-19888)

Solution

Update the pgbouncer library and its related packages to version 1.26.0-1 or later.
