What the vulnerability does
The WP ViewSTL plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'viewstl' shortcode in all versions up to, and including, 1.0 due to insufficient input sanitization and output escaping on user supplied attributes. 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
WP ViewSTL versions 1.0 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-supplied content.
What an attacker can do
Inject malicious scripts that run in other users' browsers, potentially stealing session tokens or admin credentials.
Potential impact on your site
Any authenticated user can compromise other users' sessions or steal admin credentials through stored XSS attacks.
Conditions required to exploit
Attacker must have a low-privilege user account on the site; no user interaction required from victims.
