CVE-2023-26097

Unauthorized actions via client-side-only authorization checks

Published Apr 24, 2023 · Updated May 30, 2025

Incorrect authorization in Telindus APSAL 3.14.2022.235 b allows local authenticated users to perform unintended application actions. Authorization is enforced only in client-side application code, while the backend performs no corresponding server-side legitimacy check on requested actions. Altering the client code therefore bypasses the intended restriction and permits actions that can change application behavior.
