DescriptionNVD

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.

AnalysisAI

Stored cross-site scripting in CI HUB Connector plugin for WordPress up to version 1.2.106 allows authenticated attackers with Contributor-level access or above to inject arbitrary JavaScript through the 'id' attribute of the cihub_metadata shortcode, which executes in the context of any user visiting the injected page. The vulnerability stems from insufficient input sanitization and output escaping in the shortcode handler, enabling persistent XSS attacks that can compromise site visitors and administrative accounts.
