# CVE-2026-89295: Unauthenticated memory-exhaustion denial of service in Eclipse Mnestix AAS Generator unbounded count parameter

Status: published. Published: 2026-11-03. Updated: 2026-11-03.

In Eclipse Mnestix AAS Generator versions 0.1.0 up until but excluding 1.5.0, a practical upper bound on the client-supplied count parameter of the GET /api/v1/IdGenerator/submodelIds/{count} and GET /api/v2/IdGenerator/submodelIds/{count} endpoints is not enforced. The service generates and retains identifiers in memory before returning a response. A remote unauthenticated attacker can submit a large count to cause excessive memory consumption, potentially resulting in denial of service. Exploitation requires network access to the endpoint and successful retrieval of the ID-generation configuration from the configured backend repository.
