CVE-2026-76201Network attack vector

Privilege escalation via stored form-field script injection

Published Sep 8, 2026 · Updated Sep 9, 2026

Stored XSS in Adobe Commerce and Magento Open Source August 2026 releases and earlier allows remote attackers to escalate privileges via crafted input. Affected form fields store attacker-controlled input without adequate neutralization, causing a victim's browser to execute injected JavaScript. Exploitation requires no credentials but does require a victim to view the page containing the stored field, exposing the victim's account or session to elevated attacker control.
