Echo: pgbouncer: security update to 1.26.1

high Tenable Self-Hosted Container Security Plugin ID 476417

Description

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

- An infinite loop in PgBouncer 1.20.0 through 1.26.0 allows an unauthenticated remote attacker to cause a
denial of service. A StartupMessage whose options parameter contains an empty parameter name, such as
"-c=", makes the ignore_startup_parameters list lookup loop forever. Because PgBouncer serves all clients
from a single process, this saturates a CPU core and makes PgBouncer unresponsive to all clients until the
process is restarted. (CVE-2026-107349)

Solution

Update the pgbouncer library and its related packages to version 1.26.1 or later.
