Overview

CVE-2026-18325 is a high-severity vulnerability. It was published on August 6, 2026 and has a CVSS 3.1 base score of 7.2 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.2, rated HIGH. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical description

The Forminator Forms – Contact Form, Payment Form & Custom Form Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Forged Upload Record via Select Field in all versions up to, and including, 1.56.1 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The exploit is possible because Forminator_Core::sanitize_array() skips all filtering for keys prefixed with 'select-', and set_field_data() treats a submitted 'return' member as a trusted internal flag — allowing an unauthenticated attacker to forge and persist a complete upload field record with an arbitrary file_url value without any sanitization or validation.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
