Executive Summary

This vulnerability is a Stored Cross-Site Scripting (XSS) flaw in the GamiPress plugin for WordPress. It allows authenticated attackers with contributor-level access or higher to inject malicious scripts via the 'gamipress_rank' shortcode. The issue arises from insufficient input sanitization and output escaping in versions up to 7.9.9.1.

Detection Guidance

Check WordPress sites using GamiPress plugin versions up to 7.9.9.1. Look for suspicious scripts in pages using the 'gamipress_rank' shortcode. Inspect page source for injected web scripts or unusual content.

Impact Analysis

An attacker could inject scripts that execute when users access infected pages. This may lead to unauthorized actions on behalf of users, data theft, or defacement of the website. Users with contributor access or above are the primary risk group.

Compliance Impact

This vulnerability could compromise user data confidentiality, potentially violating GDPR and HIPAA requirements for data protection. A successful exploit may lead to unauthorized access to sensitive information, triggering compliance violations and legal consequences.
