What the vulnerability does
The Mmm Unity Loader plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘attributes’ parameter in all versions up to, and including, 1.0 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
Mmm Unity Loader versions 1.0 and earlier contain a cross-site scripting (XSS) vulnerability that allows an authenticated attacker to inject malicious scripts. The vulnerability has scope change, meaning the impact can extend beyond the vulnerable component itself. Low-privileged users can exploit this without user interaction to compromise site integrity and access sensitive data.
What an attacker can do
Inject malicious scripts that execute in other users' browsers and modify site content or steal data.
Potential impact on your site
Authenticated users with low privileges can inject scripts affecting other users and site functionality.
Conditions required to exploit
Attacker must have a low-privilege account on the site; no user interaction required.
