Administrative action forgery via undisclosed request
Published Jan 5, 2024 · Updated Apr 28, 2026
CSRF in CleanTalk Spam protection, Honeypot, Anti-Spam 6.20 and earlier allows remote attackers to trigger administrative actions. The CNA and vendor-linked advisory do not disclose the affected request, handler, or missing validation operation, so the exact code-level mechanism remains publicly undisclosed. Exploitation requires an authenticated administrator to follow a crafted link or visit an attacker-controlled page; the published impact is limited to unauthorized state changes.
