What the vulnerability does
The Events Listing Widget plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'Event URL' parameter in all versions up to, and including, 1.3.4 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Author-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
The Events Listing Widget contains a cross-site scripting (XSS) vulnerability in versions up to 1.3.4. An authenticated user with low privileges can inject malicious scripts that execute in other users' browsers, potentially stealing session data or performing actions on their behalf. The vulnerability affects the entire application scope due to how the widget processes and displays user input.
What an attacker can do
Inject malicious scripts that run in other users' browsers and steal their session data or perform actions as them.
Potential impact on your site
Authenticated users can compromise other users' accounts and sessions through stored or reflected XSS attacks.
