FundEngine vulnerabilities

The FundEngine plugin version 1.7.8 and earlier contains a broken access control vulnerability exploitable by Subscriber-level users. An attacker can gain unauthorized access to functions or data.

Unauthenticated PHP Object Injection vulnerability in the FundEngine plugin. Affects versions up to 1.7.9.

An unauthenticated attacker can perform PHP Object Injection in FundEngine versions up to 1.7.9.

The FundEngine – Donation and Crowdfunding Platform plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'wfp_featured_video_url' parameter in all versions up to, and including, 1.8.1 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The REST endpoint used to submit the video URL has its permission_callback set to __return_true, meaning any authenticated user — including those with Subscriber-level access — can reach the vulnerable code path.

The FundEngine – Donation and Crowdfunding Platform plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 1.8.1. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with subscriber-level access and above, to modify arbitrary posts and pages — overwriting title and content, and seizing ownership by supplying an attacker-controlled post_author integer that bypasses wp_kses_post sanitization. The wp_rest nonce required by the handler is trivially obtainable by any logged-in user via /wp-admin/admin-ajax.php?action=rest-nonce and therefore does not constitute an authorization barrier.

The FundEngine WordPress plugin has a missing authorization vulnerability, allowing exploitation of incorrectly configured access control security levels. This issue affects versions up to and including 1.7.6.
