Technical details

The GamiPress plugin for WordPress is vulnerable to Stored Cross-Site Scripting (XSS) due to insufficient input sanitization and output escaping on the 'heading_size' attribute within its shortcode handler. While WordPress typically applies 'wp_kses_post' filters during post saving, this vulnerability bypasses that protection because the malicious payload is stored as inert shortcode text and only rendered into dangerous HTML at runtime. Authenticated attackers with contributor-level permissions or higher can exploit this to inject arbitrary web scripts. The vulnerability exists in all versions up to and including 7.9.9.1.
