What the vulnerability does
The Category Image plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'tag-image' parameter in all versions up to, and including, 2.0 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Editor-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
Category Image versions 2.0 and earlier contain a cross-site scripting vulnerability in the admin interface. An attacker with high-level admin privileges can inject malicious scripts that execute in other administrators' browsers, potentially affecting site-wide functionality. The vulnerability requires high attack complexity and does not require user interaction from the victim.
What an attacker can do
Inject malicious scripts that run in other admins' browsers to steal data or modify site settings.
Potential impact on your site
Compromised admin accounts could allow malicious admins to inject persistent scripts affecting all site administrators.
Conditions required to exploit
Attacker must have high-level admin account access; no user interaction required from victim.
