CVE, Research URL: CVE-2026-8891
Home page URL: Security reports for BitForm – Data management solution for WordPress
Application: BitForm – Data management solution for WordPress
Date: May 27, 2026
Research Description: The BitForm plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'bitform' shortcode in versions up to, and including, 1.1.0. This is due to insufficient input sanitization and output escaping on user-supplied shortcode attributes ('width' and 'height') in the Shortcode::shortcode() function, which are interpolated directly into the 'style' attribute of an <iframe> element. 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 1.1.0.
Status: vulnerable
