What the vulnerability does
The Product Subtitle for WooCommerce plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘htmlTag’ parameter in all versions up to, and including, 1.3.9 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
Product Subtitle for WooCommerce versions 1.3.9 and earlier contain a cross-site scripting (XSS) vulnerability. An attacker with low-level site access can inject malicious scripts that execute in other users' browsers, potentially compromising their sessions or stealing data. The vulnerability affects the site's scope, meaning impacts may extend beyond the plugin itself.
What an attacker can do
Inject malicious scripts that run in other users' browsers and steal their session data or perform actions on their behalf.
Potential impact on your site
Site visitors and administrators could have their sessions hijacked or be tricked into performing unintended actions by an attacker with basic site access.
Conditions required to exploit
Attacker needs a low-privilege account on the site (e.g., subscriber or contributor role). No user interaction required.
