CVE-2026-102774: 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 Image 'alt' Attribute in Community Post Content in all versions up to, and including, 1.12.1 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The entity-encoded payload bypasses server-side wpkses filtering because kses permits the img/alt tag combination and does not normalize entities inside attribute values; the decode occurs client-side when GLightbox reads the .alt DOM property and assigns the result to innerHTML.

Frequently Asked Questions
Does exploitation require administrator-level access?
No. An authenticated user with subscriber-level access or higher can inject the malicious content.
What causes the injected payload to execute?
Execution occurs when a user accesses a page containing the injected community post content. GLightbox decodes the image alt attribute client-side and assigns the result to innerHTML.
