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

Quick assessment

Affected
Eclipse Foundation Eclipse Mnestix
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

在 Eclipse Mnestix AAS Generator 0.1.0 至 1.5.0（不含 1.5.0）版本中，未对 和 端点中由客户端提供的 参数实施实际的上限约束。该服务在返回响应之前，会在内存中生成并保留标识符。远程未认证攻击者可提交一个过大的 值，导致内存过度消耗，进而可能引发拒绝服务（DoS）攻击。利用此漏洞需要能够访问该端点的网络权限，并成功从已配置的后端存储库中获取 ID 生成配置。

Vulnerability Title
Unauthenticated memory-exhaustion denial of service in Eclipse Mnestix AAS Generator unbounded count parameter
Source: CVE Program / CVE List V5
Vulnerability Description
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.
