CVE, Research URL: CVE-2025-13975
Home page URL: Security reports for Contact Form 7 with ChatWork
Application: Contact Form 7 with ChatWork
Published on: Dec 12, 2025
Research Description: The Contact Form 7 with ChatWork plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'api_token' and 'roomid' settings in all versions up to, and including, 1.1.0 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level access, to inject arbitrary web scripts in pages that will execute whenever a user accesses the settings page. This only affects multi-site installations and installations where unfiltered_html has been disabled.
Affected versions: max 1.1.0.
Status: vulnerable
