CVE-2026-44547: ChurchCRM public API login bypasses 2FA and lockout

CVE-2026-44547 · published 5 months ago
Summary

Versions 7.2.0 through 7.2.2 of ChurchCRM still allow someone to log in through the public API without needing two‑factor authentication or triggering account lockout. This means an attacker could gain access to user accounts even if extra security measures are in place. Upgrade to ChurchCRM 7.3.1 or later to close the gap.
