CVE-2026-89295: Eclipse Mnestix AAS Generator unbounded memory allocation in ID generation endpoint

CVE-2026-89295 · Severity: info · Published 2026-11-03

Eclipse Mnestix AAS Generator is a component that generates identifiers for Asset Administration Shell (AAS) models used in industrial automation systems.

Technical details

The GET /api/v1/IdGenerator/submodelIds/{count} and /api/v2/IdGenerator/submodelIds/{count} endpoints accept an unbounded unsigned integer count parameter without validation, then allocate a list of that many GUID strings in memory before returning. The authentication handler unconditionally grants admin.write scope to all GET requests without credential verification. An attacker can submit count=4294967295 or similar to trigger out-of-memory conditions, causing denial of service.

Affected products

Eclipse Mnestix AAS Generator 0.1.0 up to but excluding 1.5.0
