Technical details

The GiveWP plugin for WordPress is vulnerable to Stored Cross-Site Scripting (XSS) due to insufficient input sanitization and output escaping on the 'sequoia[introduction][image]' parameter. Authenticated attackers with 'Give Worker' level access or higher can inject arbitrary web scripts into the database. These scripts will execute in the context of any user's browser who visits the affected donation form or administrative page. The vulnerability exists in all versions up to and including 4.16.1. A patch is expected in subsequent releases to properly sanitize the affected metadata fields.
