CVE-2026-102774 Details
Description
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 wp_kses 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.
A stored DOM-based cross-site scripting vulnerability has been identified in the SureDash – Community, Courses & Member Dashboard plugin for WordPress, affecting all versions through 1.12.1. The vulnerability arises from inadequate input sanitization and output escaping, allowing authenticated attackers with subscriber-level access and above to inject arbitrary web scripts into pages. These scripts execute when a user accesses the compromised page. The issue exploits the image 'alt' attribute in community post content, bypassing server-side wp_kses filtering because the kses library allows the img/alt tag combination and fails to normalize entities within attribute values. The payload is decoded client-side by GLightbox, which reads the .alt DOM property and transfers the result to innerHTML.
Users are advised to update the SureDash WordPress plugin to version 1.12.2 or a newer patched version.
