What the vulnerability does
The Sphere Manager plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'width' parameter in the 'show_sphere_image' shortcode in all versions up to, and including, 1.0.2 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
Sphere Manager versions 1.0.2 and earlier contain a cross-site scripting vulnerability that allows authenticated users to inject malicious scripts affecting other users and administrators. The vulnerability has a changed scope, meaning the impact extends beyond the vulnerable component itself. An attacker with low-level credentials can inject code that executes in other users' browsers without requiring user interaction.
What an attacker can do
Inject malicious scripts that execute in other users' browsers, potentially stealing session tokens or performing actions on their behalf.
Potential impact on your site
Authenticated users can compromise other users' accounts or sessions; administrators may be targeted to gain higher-level access.
Conditions required to exploit
Attacker must have a low-privilege account on the site; no user interaction required from the victim.
