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...

Linux Distros Unpatched Vulnerability : CVE-2026-6669

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - 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 maliciou...

CVE-2026-85716

A flaw was found in the AsyncHttpClient AHC library. This vulnerability allows a remote attacker to impersonate the server on a non-TLS Transport Layer Security or compromised network. The library's authentication process for SCRAM and Digest mutual-authentication does not properly verify server...

CVE-2026-6669

A flaw was found in PgBouncer. A malicious or compromised PostgreSQL backend can exploit a missing upper bound on the key derivation iteration count during SCRAM Salted Challenge Response Authentication Mechanism authentication. This can lead to uncontrolled CPU consumption in PgBouncer,...

CVE-2026-19888

A flaw was found in PgBouncer. Missing validation of a mandatory attribute in the SCRAM client-final-message parser allows an unauthenticated remote attacker to crash the process. By sending a malformed message, the parser can report success while a required value remains unset, leading to a NULL...
