What the vulnerability does
The Any News Ticker plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'any-ticker' shortcode in all versions up to, and including, 3.1.1 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
Any News Ticker versions 3.1.1 and earlier contain a cross-site scripting (XSS) vulnerability. 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 site scope due to how the application processes user input.
What an attacker can do
Inject JavaScript code that runs in other users' browsers and steals their session data or performs actions as them.
Potential impact on your site
Authenticated users can compromise other users' accounts and sessions without their knowledge or consent.
Conditions required to exploit
Attacker must have a low-privilege user account on the site; no user interaction required from victims.
