CVE-2026-15730: Rubengc Gamipress – Gamification Plugin To Reward Points, Achievements, Badges & Ranks In WordPress

Medium severity, CVSS 6.4. EPSS: 0.4% chance of exploitation in the next 30 days.

The GamiPress – Gamification plugin to reward points, achievements, badges & ranks in WordPress plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'heading_size' Shortcode Attribute in all versions up to, and including, 7.9.9.1 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 wp_kses_post filter applied at post save does not neutralize this payload because only the inert shortcode text is stored in post_content; the dangerous HTML is synthesized at render time by the shortcode handler, entirely bypassing save-time sanitization.
