Description

Unbounded SCRAM iteration count allows a malicious server to cause CPU-exhaustion denial of service

Details
Package postgres-protocol
Version 0.6.11
URL https://github.com/rust-postgres/rust-postgres/commit/d40097a36a85068ea50a3afbf0ce154ba439e7f0
Date 2026-06-12
Patched versions >=0.6.12
Unaffected versions <0.3.0

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.

Applications that connect only to a trusted database are not exposed; the risk
applies to clients that may connect to untrusted or user-supplied servers, or
whose connection can be intercepted by a man-in-the-middle.

See advisory page for additional details.
