Phishing via unvalidated external redirects

Published Mar 6, 2026 · Updated Mar 6, 2026

Open redirect in Kings Plugins B2BKing Premium before 5.4.20 allows remote attackers to direct users to phishing sites. The published advisory does not identify the affected endpoint or the untrusted URL value that the plugin passes to its redirect logic. Exploitation requires a user to follow a crafted link, after which the browser leaves the trusted store for an attacker-chosen site; no direct data modification or service interruption is reported.
