Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

SI-2 Flaw Remediation good match

prevent

Directly remediates the missing file type validation flaw in the plugin's set_featured_image_from_external_url() function through timely patching.

SI-10 Information Input Validation good match

prevent

Mandates validation of information inputs such as external URLs and file types used for featured images, preventing arbitrary file uploads.

CM-7 Least Functionality good match

prevent

Restricts unnecessary functionality by disabling plugins or workflow triggers that allow unauthenticated featured image setting from external sources.

NVD Description

The Tablesome Table – Contact Form DB – WPForms, CF7, Gravity, Forminator, Fluent plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the set_featured_image_from_external_url() function in all versions up to, and including, 1.1.32.…

This makes it possible for unauthenticated attackers to upload arbitrary files on the affected site's server which may make remote code execution possible in configurations where unauthenticated users have been provided with a method for adding featured images, and the workflow trigger is created.
