Stored XSS in SureDash WordPress Plugin via draweropenverposition Block

Publication date: 2026-08-16

Last updated on: 2026-08-16

Assigner: Wordfence

Description
The SureDash – Community, Courses & Member Dashboard plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'draweropenverposition' Block/Shortcode Attribute in all versions up to, and including, 1.10.3 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The injected payload is stored inside the block-delimiter HTML comment's JSON, which wp_kses_post does not neutralize on save, and is only interpolated into the rendered style attribute at display time without esc_attr() escaping, allowing a double-quote to break out of the attribute and introduce arbitrary HTML event handlers.

Executive Summary

This vulnerability is a Stored Cross-Site Scripting (XSS) flaw in the SureDash WordPress plugin. It allows authenticated attackers with contributor-level access or higher to inject malicious scripts into web pages via a specific block/shortcode attribute called 'draweropenverposition'. The input is not properly sanitized, and the output is not escaped, enabling the scripts to execute when users visit the affected pages.

Detection Guidance

To detect this vulnerability, inspect WordPress sites using the SureDash plugin versions up to 1.10.3 for malicious payloads in the 'draweropenverposition' block/shortcode attribute. Check for stored XSS in block-delimiter HTML comments or style attributes. Use commands like grep to search for suspicious patterns in plugin files or database entries.

Impact Analysis

If exploited, this vulnerability could allow attackers to steal user sessions, deface websites, or redirect users to malicious sites. It requires an attacker to have at least contributor-level access, but once exploited, it affects all visitors to the compromised pages.

Compliance Impact

This vulnerability could lead to unauthorized access to user data, violating GDPR's data protection requirements and HIPAA's safeguards for protected health information. Organizations using the affected plugin may face compliance breaches if the flaw is exploited.

Mitigation Strategies

Update the SureDash plugin to the latest version beyond 1.10.3 to ensure the vulnerability is patched. Remove or disable the plugin if an update is not available. Monitor for any suspicious activity or unauthorized changes in WordPress pages.
