What the vulnerability does
The faq shortocde plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'color' shortcode attribute in the 'faq' shortcode in all versions up to, and including, 1.0 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

The FAQ Shortcode plugin contains a stored cross-site scripting (XSS) vulnerability in versions up to 1.0. An authenticated user with low privileges can inject malicious scripts into FAQ content that execute in the browsers of other site visitors and administrators. The vulnerability affects the entire site scope due to how the shortcode is processed and rendered across pages.
What an attacker can do
Inject malicious JavaScript that runs in other users' browsers when they view pages with the affected shortcode.
Potential impact on your site
Visitors and admins viewing FAQ content could have sessions hijacked, credentials stolen, or be redirected to malicious sites.
