What the vulnerability does
The Zenost Shortcodes plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'link' and 'target' parameters in the `button` shortcode in all versions up to, and including, 1.0 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
Zenost Shortcodes versions 1.0 and earlier contain a stored cross-site scripting (XSS) vulnerability. An authenticated user with low privileges can inject malicious scripts into shortcode content. When other users view pages containing the affected shortcodes, the injected scripts execute in their browsers, potentially allowing session hijacking, credential theft, or malware distribution.
What an attacker can do
Inject malicious scripts that execute when other users view affected pages.
Potential impact on your site
Compromised user accounts, stolen session tokens, or malware distribution to site visitors.
Conditions required to exploit
Attacker must have a low-privilege authenticated account on the site.
