What the vulnerability does
The CI HUB Connector plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'id' attribute of the `cihub_metadata` shortcode in all versions up to, and including, 1.2.106 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
CI HUB Connector versions 1.2.106 and earlier contain a cross-site scripting (XSS) vulnerability that allows authenticated users to inject malicious scripts. The vulnerability has scope change, meaning injected code can affect other users or components beyond the vulnerable input point. An attacker with low-level credentials can exploit this without user interaction to compromise site integrity and read sensitive data.
What an attacker can do
Inject malicious scripts that execute in other users' browsers and affect other site components.
Potential impact on your site
Authenticated attackers can deface content, steal session tokens, or redirect users to malicious sites.
Conditions required to exploit
Attacker must have a low-privilege account on the site; no user interaction required.
