Phishing via insufficient redirect URL validation

Published Dec 9, 2025 · Updated Apr 28, 2026

Open redirect in FBS Flexmls IDX 3.15.7 and earlier allows remote attackers to redirect visitors via crafted links. A supplied redirect URL receives insufficient validation, but public records do not disclose the affected endpoint, parameter, or function. Exploitation requires a visitor to follow the link; navigation can reach an attacker-controlled site for phishing, with no reported service interruption.
