CVE-2026-4353

MEDIUM

CI HUB Connector <= 1.2.106 - Authenticated (Contributor+) Stored Cross-Site Scripting via 'id' Shortcode Attribute

Title source: cna

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.
