CVE-2024-37031Network attack vector

Stored script execution via unescaped form legends

Published Jun 3, 2024 · Updated Feb 13, 2025

Stored XSS in Active Admin before 3.2.2 and 4.0.0.beta1 through 4.0.0.beta6 allows remote attackers to execute script in administrator browsers. The form builder places a dynamic resource name into an implicit or explicit form legend without HTML escaping, so stored markup becomes active script. Exploitation requires a public entity-creation path that accepts an arbitrary name and an administrator who later edits that entity in the private backend.
