Authorization Bypass in FundEngine WordPress Plugin

Publication date: 2026-08-25

Last updated on: 2026-08-25

Assigner: Wordfence

Description
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.

Executive Summary

The FundEngine WordPress plugin up to version 1.8.1 has an authorization bypass flaw. It fails to verify user permissions properly, allowing authenticated attackers with subscriber-level access or higher to modify any post or page. Attackers can overwrite titles and content and even take ownership by setting a malicious post_author value.

Detection Guidance

Check for unauthorized modifications to posts or pages by reviewing WordPress admin logs and comparing recent changes. Look for unusual activity from subscriber-level accounts. Inspect the plugin version in WordPress admin under Plugins to confirm if it is up to 1.8.1.

Impact Analysis

If you use this plugin, attackers could alter your website content, change ownership of posts, or deface pages. This could damage your site's integrity, reputation, or SEO rankings. The attack requires only a subscriber account, making it accessible to low-privilege users.

Compliance Impact

This vulnerability could lead to unauthorized content changes, potentially violating data integrity requirements in GDPR or HIPAA. If sensitive data is altered or exposed due to this flaw, it may result in compliance breaches and legal consequences.

Mitigation Strategies

Update the FundEngine plugin to the latest version if available. Temporarily disable the plugin if no update is available. Restrict subscriber-level access to only trusted users and monitor for unauthorized changes.
