Description

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.

Affected WordPress components

A confirmed match is backed by the plugin or theme slug. A possible match is based on the product name only and should be verified.
