What the vulnerability does
The Freemind Viewer plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'freemind' shortcode in all versions up to, and including, 1.0 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
Freemind Viewer versions 1.0 and earlier contain a cross-site scripting vulnerability that allows an authenticated attacker to inject malicious scripts affecting other users. The vulnerability has scope impact, meaning the attack can extend beyond the vulnerable component itself. Low-level authentication is required, but no user interaction is needed for exploitation.
What an attacker can do
Inject malicious scripts that execute in other users' browsers and modify site content or steal session data.
Potential impact on your site
Authenticated users can inject scripts affecting other visitors; data theft and site defacement are possible.
Conditions required to exploit
Attacker must have a low-level user account; no user interaction required.
