What the vulnerability does
The WP SoundSystem plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's wpsstm-track shortcode in all versions up to, and including, 3.4.2 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 SoundSystem versions 3.4.2 and earlier contain a cross-site scripting (XSS) vulnerability that allows authenticated users to inject malicious scripts. The vulnerability has a changed scope, meaning the impact can extend beyond the vulnerable component itself. An attacker with low-level WordPress access can craft payloads that affect other users or site functionality.
What an attacker can do
Inject malicious JavaScript that runs 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-level WordPress user account (e.g., subscriber or contributor role).
