GHSA-5X78-73V4-XG6W postgres-protocol: Unbounded SCRAM iteration count allows a malicious server to cause CPU-exhaustion denial of service

A malicious, compromised, or man-in-the-middle server can supply an arbitrarily large SCRAM-SHA-256 PBKDF2 iteration count during authentication. The client runs it inline with no upper bound, pinning a tokio worker thread for minutes per connection, possibly stalling the whole async runtime...

GO-2026-6168 WITHDRAWN: Unbounded iteration count causes CPU denial of service in github.com/lib/pq/scram

This report has been withdrawn with reason: "Report mistakenly added without having CVE / GHSA associated". The SCRAM client in github.com/lib/pq/scram accepts an attacker-controlled iteration count with no upper bound and immediately performs that many PBKDF2-style HMAC rounds. A PostgreSQL...

SUSE CVE-2026-14672

Observable response discrepancy in PostgreSQL SCRAM authentication allows an unauthenticated user to test the existence of a user via observing the SCRAM iteration count. This requires the probed user to have a non-default scramiterations count, because the authentication challenge for a...
