Deeper analysis

CVE-2026-5192 is a Path Traversal vulnerability (CWE-22) affecting the Forminator Forms – Contact Form, Payment Form & Custom Form Builder plugin for WordPress in versions up to and including 1.52.1. The flaw occurs via the 'upload-1[file][file_path]' parameter, enabling unauthenticated attackers to read the contents of arbitrary files on the server, which may contain sensitive information. Published on 2026-05-05, it carries a CVSS v3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N), indicating high confidentiality impact with low attack complexity.

Unauthenticated attackers can exploit this vulnerability on sites running vulnerable plugin versions where a publicly accessible form includes a File Upload field with "Save and Continue" enabled in the form's Behavior settings, and the "Save and Continue" email notification is configured to attach uploaded files. Exploitation allows remote reading of arbitrary server files, potentially exposing sensitive data such as configuration files or other non-public information.

Advisories point to mitigation via plugin updates, with a patch committed in WordPress plugin trac changeset 3500671 at https://plugins.trac.wordpress.org/changeset/3500671/forminator.
