Privilege escalation via stored form-field scripts
Published Mar 11, 2026 · Updated Mar 11, 2026
Stored XSS in Adobe Commerce 2.4.9-alpha3 and earlier allows remote authenticated users with admin rights to escalate privileges. Vulnerable form fields store attacker-controlled script content and later return it to a victim's browser; Adobe has not disclosed the specific field or code locus. Exploitation requires an administrator to inject the script and another user to browse the affected page, enabling victim session takeover.
