Sensitive data disclosure via backend path traversal
Published Mar 30, 2026 · Updated Mar 30, 2026
Path traversal in WAGO Device Sphere before 1.2.2 and Solution Builder before 2.4.2 allows remote attackers to read sensitive data. The products insufficiently filter special path elements used to select backend system-communication components, so traversal escapes the intended component scope. No authentication or user interaction is required; the published advisory does not identify the affected endpoint or specific data exposed.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
