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 ...

The vulnerability of the SCRAM (Salted Challenge Response Authentication Mechanism) mechanism in the PostgreSQL PgBouncer connection pool allows a attacker to induce a service failure.

The vulnerability of the SCRAM Salted Challenge Response Authentication Mechanism mechanism in the PostgreSQL PgBouncer connection pool software is related to uncontrolled resource consumption due to the lack of a limit on the number of iterations required to generate a password. Exploiting this...

The vulnerability of the SCRAM (Salted Challenge Response Authentication Mechanism) mechanism in the PostgreSQL PgBouncer connection pool allows a attacker to induce a service failure.

The vulnerability of the SCRAM Salted Challenge Response Authentication Mechanism mechanism in the PostgreSQL PgBouncer connection pool lies in the dereferencing of pointers due to the lack of validation for a required attribute in the end-message parser. Exploiting this vulnerability allows a...
