The Chartify – WordPress Chart Plugin plugin for WordPress is vulnerable to Local File Inclusion in all versions up to, and including, 2.9.5 via the 'source' parameter. This makes it possible for unauthenticated attackers to include and execute arbitrary files on the server, allowing the execution of any PHP code in those files. This can be used to bypass access controls, obtain sensitive data, or achieve code execution in cases where images and other “safe” file types can be uploaded and included.

→Exploit requests are unauthenticated POST requests to /wp-admin/admin-ajax.php with the 'source' parameter containing directory traversal sequences (../../) and the POST body containing action=ays_chart_admin_ajax&function=display_plugin_charts_page ↗
→Successful exploitation of the first stage sets a PHPSESSID cookie in the response header, which can be used as an indicator of a successful LFI probe ↗
→Successful exploitation of the second stage returns HTTP 200 with body containing both 'ays-chart-heading-box' and 'View Documentation', indicating arbitrary file inclusion was achieved ↗
→The vulnerable parameter is 'source' passed via GET query string to admin-ajax.php; monitor for traversal patterns (e.g., '../') in the source parameter of requests to admin-ajax.php ↗

·The exploit is a two-step flow: the first HTTP request must succeed (PHPSESSID cookie present in response) before the second LFI request is sent. Detection logic should account for this chained request pattern. ↗
·The vulnerability affects all plugin versions up to and including 2.9.5; version 2.9.6 is the patched release. Scope detection rules to installations running versions <= 2.9.5. ↗
