CVE-2022-34257Network attack vector

Unauthenticated browser script execution via stored form input

Published Aug 16, 2022 · Updated Apr 23, 2025

Stored XSS in affected Adobe Commerce releases allows remote attackers to execute scripts in a victim's browser through form fields. Adobe identifies vulnerable form fields as the storage and delivery path for malicious JavaScript but does not disclose the field names or faulty encoding operation. No authentication or administrator access is required to inject the script, but a victim must browse to the page containing the poisoned field; execution is confined to the victim's browser context.
