CVE, Research URL: CVE-2026-8841
Home page URL: Security reports for Extra Settings for RocketChat
Application: Extra Settings for RocketChat
Date: Jun 09, 2026
Research Description: The Extra Settings for RocketChat plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'rocketchat' shortcode's 'title' attribute in versions up to, and including, 0.1. This is due to insufficient input sanitization and output escaping in the rxstg_shortcode() function, which concatenates the user-supplied 'title' attribute directly into HTML output. 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 versions: max 0.1.
Status: vulnerable
