CVE-2020-7050 Information

Description

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.
