CVE-2022-34466Network attack vector

Sensitive information disclosure via Workflow expression injection

Published Jul 12, 2022 · Updated Aug 3, 2024

Expression injection in Siemens Mendix Runtime 9.11 through 9.14 allows remote authenticated users to read sensitive information. Siemens identifies the Workflow subsystem but does not publish the affected function or exact unsafe expression-evaluation path. Exploitation requires an authenticated account and an application using the Workflow visual language, and the disclosed impact is limited to reading sensitive information.
