HIGH CVE-2026-16649 Deferred

Gravity Forms tooltip rendering permits unauthenticated stored XSS

Gravity Forms through 2.10.5 allows an unauthenticated form submitter to place a payload in a Post Body field that survives wp_kses_post(). Client-side tooltip code browser-decodes the aria-label value, reparses it as innerHTML, and removes script elements without removing event-handler attributes, allowing stored JavaScript execution when the affected content is viewed.

Technical description

The Gravity Forms plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Post Body Field Value in all versions up to, and including, 2.10.5 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The exploit survives save-time sanitization because wp_kses_post allows the required HTML tags and attributes, and the client-side tooltip script re-parses the browser-decoded aria-label value as innerHTML while only stripping script elements, leaving onerror and other event-handler attributes fully intact and executable.
