SureDash <= 1.12.1 - Authenticated (Subscriber+) Stored DOM-Based Cross-Site Scripting via Image 'alt' Attribute in Community Post Content
The SureDash – Community, Courses & Member Dashboard plugin for WordPress is vulnerable to Stored DOM-Based Cross-Site Scripting via the image alt attribute in community post content in all versions up to, and including, 1.12.1. This issue stems from insufficient input sanitization and output escaping, allowing authenticated attackers with subscriber-level permissions or higher to inject arbitrary web scripts into pages that execute whenever a user accesses an injected page. The entity-encoded payload bypasses server-side wp_kses filtering because kses permits the img/alt tag combination and does not normalize entities inside attribute values. Decoding occurs client-side when GLightbox reads the .alt DOM property and assigns the result to innerHTML.
What to do
Update the SureDash – Community, Courses & Member Dashboard plugin to version 1.12.2 or later.
