Summary
Phorum is prone to multiple HTML-injection vulnerabilities because it fails to sufficiently sanitize user-supplied data.
Attacker-supplied HTML or JavaScript code could run in the context of the affected site, potentially allowing the attacker to steal cookie- based authentication credentials and to control how the site is rendered to the user
other attacks are also possible.
Versions prior to Phorum 5.2.12a are vulnerable.
Solution
Vendor fixes are available. Please see the references for details.
