CVE-2026-4133 - Textp2p Texting Widget Plugin

CVE-2026-4133

The TextP2P Texting Widget plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to and including 1.7. This is due to missing nonce validation in the imTextP2POptionPage() function which processes settings updates. The form at line 314 does not include a wp_nonce_field(), and the POST handler at line 7 does not call check_admin_referer() or wp_verify_nonce() before processing settings changes. This makes it possible for unauthenticated attackers to update all plugin settings including chat widget titles, messages, API credentials, colors, and reCAPTCHA configuration via a forged request, granted they can trick a site administrator into performing an action such as clicking a link.
