Executive Summary

This vulnerability affects the GiveWP WordPress plugin versions before 4.16.9. It allows unauthenticated users to execute arbitrary shortcodes by exploiting improper handling of donor-supplied values. The plugin does not remove shortcode delimiters from these values before rendering them on public pages, and the shortcode stripping can be bypassed through nesting.

Detection Guidance

Check if your GiveWP plugin version is below 4.16.9. Use WordPress admin to view the plugin version or run the command: wp plugin list --name=givewp. If vulnerable, inspect public pages for unexpected shortcode execution by testing with nested shortcodes.

Impact Analysis

An attacker could exploit this to execute malicious shortcodes on your site, potentially leading to unauthorized actions, data leaks, or further compromise of your WordPress installation. Since it requires no authentication, any visitor could potentially trigger this issue.

Compliance Impact

This vulnerability could lead to unauthorized data access or modification, violating GDPR or HIPAA requirements for data protection and access control. Organizations using affected versions may face compliance violations if exploited.

Mitigation Strategies

Update the GiveWP plugin to version 4.16.9 or later immediately. If updating is not possible, disable the plugin temporarily until the update is applied. Review public pages for signs of exploitation.
