CVE-2026-4353: Cihubconnector Ci Hub Connector

Medium severity, CVSS 6.4. EPSS: 0.3% chance of exploitation in the next 30 days.

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.
