Vvveb through 1.0.8.6 contains a stored cross-site scripting vulnerability that allows low-privilege author or vendor users to inject script by bypassing the regex blacklist in sanitizeHTML(). Attackers can save post or product content with unclosed event-handler tags or javascript: entities to execute script for anonymous visitors and admins, enabling session or CSRF-token theft.
