Summary
Codologic Codoforum through 4.8.4 allows a DOM-based XSS. While creating a new topic as a normal user, it is possible to add a poll that is automatically loaded in the DOM once the thread/topic is opened. Because session cookies lack the HttpOnly flag, it is possible to steal authentication cookies and take over accounts.
Exploit prediction
0.54% chance of exploitation in the next 30 days, higher than 45% of all scored CVEs (FIRST EPSS, 2026-11-08).
