What the vulnerability does
The Appzend theme for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘progressbarLayout’ parameter in all versions up to, and including, 1.2.6 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
Appzend versions 1.2.6 and earlier contain a stored cross-site scripting (XSS) vulnerability. An authenticated user with low privileges can inject malicious scripts that execute in the browsers of other users, including site administrators. The vulnerability affects the entire site scope due to how the application processes and displays user-controlled input without proper sanitization.
What an attacker can do
Inject malicious scripts that run in other users' browsers, potentially stealing session tokens or performing actions as those users.
Potential impact on your site
Attackers with basic user accounts can compromise admin sessions and modify site content or settings without additional authorization.
Conditions required to exploit
Attacker must have a low-privilege authenticated account on the site; no user interaction required from victims.
