CVE-2024-13377Network attack vector

Stored XSS via unsanitized alt parameter

Published Jan 17, 2025 · Updated Apr 8, 2026

Stored XSS in Rocketgenius Gravity Forms 2.9.1.3 and earlier allows remote attackers to inject scripts through the alt parameter. The alt-parameter handling accepts attacker-controlled text without sufficient input sanitization and later renders it without output escaping. No account is required; execution occurs when a user accesses a page containing the injected value, exposing that browser session to attacker-supplied script.
