The Formidable Charts plugin for WordPress is susceptible to a Directory Traversal vulnerability that allows unauthenticated attackers to access and read arbitrary files on the server through the 'frm_graph' parameter. This could lead to the exposure of sensitive information, particularly if the wp-content/uploads/frm-charts/ directory is present. WordPress site administrators using this plugin should prioritize patching to mitigate potential data breaches.

Original NVD Description

The Formidable Charts plugin for WordPress is vulnerable to Directory Traversal in all versions up to, and including, 2.0.1 via the 'frm_graph' parameter. This makes it possible for unauthenticated attackers to read the contents of arbitrary files on the server, which can contain sensitive information. Successful exploitation requires Formidable Forms Lite, Formidable Forms Pro, and Formidable Charts to be active and requires the wp-content/uploads/frm-charts/ directory to exist, normally after an image-format chart is rendered.
