Live › vulnerability › CVE-2026-115301
The Contact Form by Supsystic WordPress plugin before 1.11.1 renders stored form-editor content through a template engine without sandboxing it. An administrator can inject template code that runs on the server, and the payload executes for any visitor who loads a page with the form, exposing secrets such as salts and database credentials.

Sites running the Contact Form by Supsystic WordPress plugin before version 1.11.1 are exposed, since any visitor to a page containing a form triggers the stored payload. Sites without this plugin, or already on 1.11.1 or later, are not affected. Exploitation first requires an administrator account to store the payload.

1.11.1 are in the stated range.1.11.1 or later (the sources state the fix is in 1.11.1).Each row is the first time that source carried this signal. The analyst’s rows are its own findings.
The Contact Form by Supsystic WordPress plugin before 1.11.1 does not sandbox the template engine used to render its forms and allows stored form-editor content to reach that engine as executable template code, enabling an administrator to perform server-side template injection and execute arbitrary code on the server. The injected template is compiled and executed whenever any visitor loads a page containing the form, so the stored payload also lets an unauthenticated visitor read server-side secrets such as authentication salts and database credentials.
