Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

vantage6 是一个用于隐私保护分析的开源基础设施。在 5.0.2 及更早版本中，算法仓库的编辑权限缺乏所有权检查，导致一个算法开发者可以修改另一位开发者处于待处理或审核状态的算法。攻击者可以更改元数据，包括算法镜像或镜像标签，从而使审核人员和节点信任一个与原始提交用于审批的镜像不同的镜像。截至本次审查，尚无修复版本可用。

Vulnerability Title
vantage6: Algorithm developer can edit another developer's algorithm that is pending / under review
Source: CVE Program / CVE List V5
Vulnerability Description
vantage6 is an open-source infrastructure for privacy preserving analysis. In version 5.0.2 and earlier, the algorithm-store edit permission lacks an ownership check, allowing one algorithm developer to alter another developer's algorithm while it is pending or under review. The attacker can change metadata including the algorithm image or image tag, causing reviewers and nodes to trust a different image from the one originally submitted for approval. No fixed version is available as of this review.
