CVE-2026-21292Network attack vector

Victim-browser script execution via stored form input

Published Mar 11, 2026 · Updated Mar 11, 2026

Stored XSS in Adobe Commerce 2.4.9-alpha3 and earlier allows remote authenticated users to run script via stored form-field input. Adobe identifies vulnerable form fields but has not published their names or the code path that stores input without sufficient neutralization. A low-privileged account can persist the payload, but execution requires a victim to browse the affected page and is bounded to that browser context.
