What the vulnerability does
The Cool Tag Cloud plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'cool_tag_cloud' shortcode in all versions up to, and including, 2.29 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
Cool Tag Cloud versions 2.29 and earlier contain a stored cross-site scripting (XSS) vulnerability. An authenticated user with low privileges can inject malicious scripts into tag cloud data that execute in the browsers of other site visitors. This allows theft of session tokens, account hijacking, or malware distribution to site users.
What an attacker can do
Inject malicious JavaScript that runs in other users' browsers when they view the tag cloud.
Potential impact on your site
Site visitors' accounts can be compromised; attackers can steal credentials or inject malware into pages.
Conditions required to exploit
Attacker must have a low-privilege authenticated account on the site; no user interaction required.
