Formidable Charts <= 2.0.1 - Unauthenticated Arbitrary File Read via 'frm_graph' Parameter
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.
