CVE-2026-12421Network attack vector

Unauthenticated stored XSS via password field values

Published Jul 23, 2026 · Updated Jul 23, 2026

Stored XSS in Repute InfoSystems ARForms 7.2.1 and earlier allows remote attackers to inject scripts through password field values. The entry-record helper stores password field content without sufficient sanitization and later renders it without output escaping. Reachability requires an affected ARForms password field; accessing an injected page executes the stored script in the visitor's browser context.
