CVE-2026-84173

Quick assessment

Affected
Eclipse Foundation Eclipse Ankaios
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 Ankaios 版本 v0.5.1 至 v1.0.1 中，代理端的控制接口（Control Interface）授权器对以通配符开头的多段允许规则（allow rules）进行评估时存在错误。当一个经过身份验证的工作负载（workload）受此类规则限制时，它可以提交 或 ，其中字段掩码（field mask）为空。该请求可能被错误地授权为匹配受限规则，从而允许该工作负载读取完整的集群状态，或在其授权子树之外替换状态。这可能导致其他工作负载或集群配置发生未授权的披露或修改。只有仅由 组成的规则才

Vulnerability Title
N/A
Source: CVE Program / CVE List V5
Vulnerability Description
In Eclipse Ankaios versions v0.5.1 through v1.0.1, the agent-side Control Interface authorizer incorrectly evaluates multi-segment allow rules whose first path segment is a wildcard. An authenticated workload with access restricted by such a rule can submit a CompleteStateRequest or UpdateStateRequest with an empty field mask. The request may then be incorrectly authorized as matching the scoped rule, allowing the workload to read the complete cluster state or replace state outside its authorized subtree. This may result in unauthorized disclosure or modification of other workloads and cluster configuration. Only a rule consisting solely of * is intended to authorize an empty mask. Mitigation: Until an update containing the fix is installed, avoid multi-segment Control Interface allow-rule filter masks that begin with a wildcard, such as *.workloads.some_workload. Replace them with explicit paths such as desiredState.workloads.some_workload, where applicable. A filter mask consisting solely of * has different, intentionally unrestricted semantics and should only be used when full-state access is intended.
