NewCVE-2025-64102 Â (opens in a new tab)How to fix?
Upgrade github.com/zitadel/zitadel/internal/config/systemdefaults to version 2.71.18, 3.4.3, 4.6.0 or higher.
Overview
Affected versions of this package are vulnerable to Brute Force via insufficient enforcement of authentication attempt limits in the authentication process. An attacker can gain unauthorized access to user accounts by performing automated brute-force attacks against OTP, TOTP, or password authentication mechanisms.
Note: This is only exploitable if the lockout policy is not enabled or if resource-based APIs are used without proper mitigation.
Workaround
This vulnerability can be mitigated by enabling the optional logout policy ("Password maximum attempts") or by implementing more strict rate limits.
