Recommendation: Plan a near-term fix — a public PoC already exists.

OpenEMR 7.0.1 contains an authentication brute force vulnerability that allows attackers to bypass rate limiting protections by sending repeated login attempts to the main login endpoint. Attackers can submit POST requests with authUser and clearPass parameters to systematically test username and password combinations without account lockout restrictions.
