## Technical details

The GamiPress plugin for WordPress is vulnerable to Stored Cross-Site Scripting (XSS) due to improper neutralization of user-supplied input within the 'gamipress_rank' shortcode. The vulnerability exists in versions up to and including 7.9.9.1. An authenticated attacker with contributor-level permissions or higher can exploit this by injecting arbitrary web scripts into pages via the shortcode attributes. Because the input is not properly sanitized or escaped upon output, the script executes in the context of any user who views the compromised page. A patch has been released in the form of a changeset to address the sanitization logic.
