What the vulnerability does
The WaveSurfer-WP plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's audio shortcode in all versions up to, and including, 2.8.3 due to insufficient input sanitization and output escaping on the 'src' attribute. 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
WaveSurfer-WP versions up to 2.8.3 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 administrators. The vulnerability affects the entire site scope. Update to version 2.8.4 or later to remediate.
What an attacker can do
Inject malicious scripts that run in other users' browsers, potentially stealing session tokens or performing actions as those users.
Potential impact on your site
