Stored XSS in Charitable WordPress Plugin

Executive Summary

This vulnerability is a Stored Cross-Site Scripting (XSS) issue in the Charitable WordPress plugin before version 1.8.5.3. It occurs because the plugin fails to properly sanitize and escape a campaign image text field before displaying it in an HTML attribute. This allows users with high-privilege campaign-management roles to inject malicious scripts that execute when the front-end campaign page is viewed.
