CVE-2022-0251Network attack vector

Stored XSS via imported layout node names

Published Jan 26, 2022 · Updated Aug 2, 2024

Stored XSS in Pimcore before 10.2.10 allows remote authenticated users to execute script through imported class-layout node names. ClassDefinition Service accepts names from imported JSON layout trees and, before the fix, fails to reject HTML markup before later rendering. Exploitation requires an authenticated account permitted to import class definitions and a user to view the stored name, exposing that user's browser context to attacker-controlled script.
