What the vulnerability does
The JB News Ticker plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'id' shortcode attribute of the 'jbticker' shortcode in all versions up to, and including, 1.0. This is 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
JB News Ticker versions 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 credentials can exploit this without user interaction.
What an attacker can do
Inject malicious JavaScript that executes in other users' browsers or affects site functionality.
Potential impact on your site
Authenticated users can inject scripts affecting other visitors or site admins; potential for credential theft or malware distribution.
Conditions required to exploit
Attacker must have a low-privilege account (e.g., subscriber or contributor role) on the site.
