GO-2026-6168

>= 1.1.0
Description

(This report has been withdrawn with reason: "Report mistakenly added without having CVE / GHSA associated").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 endpoint or active network attacker can send a valid SCRAM server-first message with a large iteration count (such as i=2147483647), causing client authentication to consume excessive CPU resources before verifying the server signature.
