What the vulnerability does
The FancyTabs plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘title’ parameter in all versions up to, and including, 1.1.0 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.
Explanation of Vulnerability in Simple Terms
FancyTabs versions 1.1.0 and earlier contain a cross-site scripting (XSS) vulnerability that allows authenticated users to inject malicious scripts. The vulnerability has a changed scope, meaning injected code can affect other users or components beyond the vulnerable feature. An attacker with low-level account access can craft malicious input that executes in other users' browsers.
What an attacker can do
Inject JavaScript that runs in other users' browsers, potentially stealing session tokens or performing actions on their behalf.
Potential impact on your site
Authenticated users can inject malicious scripts affecting other site visitors; may lead to account compromise or data theft.
Conditions required to exploit
Attacker must have a low-privilege account on the site; no user interaction required from the victim.
