What the vulnerability does
The Bitspecter Suite plugin for WordPress is vulnerable to Stored Cross-Site Scripting via SVG File uploads in all versions up to, and including, 1.0.0 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Author-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses the SVG file.
Explanation of Vulnerability in Simple Terms
Bitspecter Suite versions 1.0.0 and earlier contain a cross-site scripting (XSS) vulnerability that allows authenticated users to inject malicious scripts. The vulnerability has a changed scope, meaning the impact can extend beyond the vulnerable component itself. An attacker with low-level privileges can inject code that affects other users or system components without requiring user interaction.
What an attacker can do
Inject malicious scripts that execute in other users' browsers or affect other system components.
Potential impact on your site
Authenticated users can inject scripts affecting other users' sessions, data, or system integrity.
Conditions required to exploit
Attacker must have a low-level user account on the system; no user interaction required.
