Name of the Vulnerable Software and Affected Versions
Vvveb versions prior to 1.0.8.6
Description
The HTML sanitizer fails to strip event-handler attributes when a tag contains a greater-than character within a quoted attribute value. This allows a low-privilege content author, such as those with the author or contributor role, to store a malicious payload in post or product content. When a visitor or administrator views or previews the content, the payload executes JavaScript in their browser, potentially leading to the takeover of administrator accounts.
Recommendations
Update to version 1.0.8.6.
