CVE-2026-115300 Details
Description
The Contact Form by Supsystic WordPress plugin before 1.11.1 does not validate a CSRF token or request origin on two administrator-only actions that bulk-delete captured form submissions and wipe a form's statistics, allowing attackers to permanently destroy a site's stored contact leads and analytics by tricking a logged-in administrator into sending a forged request.
A Cross-Site Request Forgery (CSRF) vulnerability has been identified in the Contact Form by Supsystic WordPress plugin, affecting versions prior to 1.11.1. The vulnerability arises because the plugin does not properly validate CSRF tokens or the origin of requests for two actions reserved for administrators. These actions allow for the bulk deletion of form submissions and the erasure of a form's statistical data. As a result, an attacker could potentially manipulate a logged-in administrator into sending a fake request, leading to the permanent loss of contact leads and analytics on the site.
Users are advised to update the Contact Form by Supsystic WordPress plugin to version 1.11.1 or later.
