Path Traversal in Formidable Charts (WordPress plugin) (CVE-2026-15990)
Summary
Path traversal in Formidable Charts (WordPress plugin) (CVE-2026-15990). Confidential information can be exposed externally.
Original description
The description as published by the source.
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.
