CVE-2026-75575Network attack vector

Account probing via unthrottled password-reset method

Published Aug 25, 2026 · Updated Aug 25, 2026

Observable response discrepancy in Rocket.Chat affected releases allows remote attackers to probe account types through an anonymous method. The sendForgotPasswordEmail Meteor method performs account lookup and password-reset delivery without registering a DDP rate-limit rule, while its boolean result distinguishes OAuth-only accounts when password changes are disabled. Unauthenticated DDP or method.callAnon HTTP access is sufficient to generate unbounded reset email from the server and enumerate that account class.
