Quick assessment

Affected
argoproj-labs argocd-mcp
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.

Argo CD MCP Server（argocd-mcp）在 0.9.0 及之前版本中存在一个路径遍历漏洞，该漏洞位于 delete_application 工具中。由于未对 applicationName 参数进行充分验证，MCP 客户端可以利用此漏洞访问非预期的 API 端点。攻击者或通过提示注入（prompt injection）操控的模型可以传入包含“../”等路径遍历序列的值（例如 ../repositories/），从而在令牌（token）所授权的角色访问控制（RBAC）权限范围内，发起经过身份验证的
