What the vulnerability does
The ShortcodeHub plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘author_link_target’ parameter in all versions up to, and including, 1.7.1 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
ShortcodeHub versions up to 1.7.1 contain a cross-site scripting (XSS) vulnerability that allows authenticated users to inject malicious scripts. The vulnerability has a changed scope, meaning injected code can affect other users and site functionality. An attacker with low-level site access can craft malicious shortcodes that execute in other users' browsers when they view affected pages.
What an attacker can do
Inject JavaScript that runs in other users' browsers, potentially stealing session tokens or modifying page content.
Potential impact on your site
Authenticated users with low privileges can inject malicious code affecting other site visitors and administrators.
Conditions required to exploit
Attacker needs a low-privilege account (e.g., contributor or subscriber role) on the site.
