What the vulnerability does
The Soundslides plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the soundslides shortcode in all versions up to, and including, 1.4.2 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
Soundslides versions 1.4.2 and earlier contain a cross-site scripting vulnerability that allows authenticated users to inject malicious scripts affecting other users on the site. The vulnerability exists because user input is not properly sanitized before being displayed. An attacker with low-level account access can craft a payload that executes in other users' browsers, potentially stealing session data or performing actions on their behalf.
What an attacker can do
Inject malicious scripts that execute in other users' browsers and steal their session data or perform actions on their behalf.
Potential impact on your site
Users' accounts and data are at risk if an authenticated attacker injects malicious scripts; site-wide impact possible due to scope change.
Conditions required to exploit
Attacker must have a low-level user account on the site; no user interaction required from the victim.
