Privilege escalation via stored form-field scripts
Published Sep 8, 2026 · Updated Sep 9, 2026
Stored XSS in Adobe Commerce, Commerce B2B, and Magento Open Source allows remote attackers to escalate privileges through form fields. Untrusted input is stored in unspecified vulnerable form fields and later rendered as executable JavaScript in a victim's browser; Adobe has not identified the field, component, or sanitization failure. Exploitation requires no authentication but requires a victim to open the page containing the stored payload, exposing that victim's account or session to elevated attacker control.
