CVE-2025-47951

Weblate is a web based localization tool. Prior to version 5.12, the verification of the second factor was not subject to rate limiting. The absence of rate limiting on the second factor endpoint allows an attacker with valid credentials to automate OTP guessing. This issue has been patched in version 5.12.
