BIT-PGBOUNCER-2026-6669 Unbounded SCRAM iteration count causes CPU exhaustion in PgBouncer

Missing upper bound on the key derivation iteration count accepted during SCRAM authentication to a backend server in PgBouncer through 1.25.2 allows a malicious or compromised PostgreSQL backend to cause uncontrolled CPU consumption in PgBouncer. The resulting key derivation cannot be interrupte...

BIT-PGBOUNCER-2026-19888 NULL pointer dereference in SCRAM client-final-message parsing in PgBouncer

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 ...
