NVD Description
Note: Versions mentioned in the description apply only to the upstream pgbouncer package and not the pgbouncer package as distributed by Wolfi.
See How to fix? for Wolfi relevant fixed versions and status.
PgBouncer before 1.25.2 did not perform an appropriate authorization check for the KILL_CLIENT admin command. All users with access to the administration console (which itself requires authorization) could run this command. It would have been correct to allow only users listed in the admin_users parameter.
