Quick assessment

Affected
AWS aws-healthomics-mcp-server
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.

AWS aws-healthomics-mcp-server是AWS公司的一个生物信息学数据管理服务。 AWS aws-healthomics-mcp-server 0.0.36之前版本存在路径遍历漏洞，该漏洞源于linting tools对受限目录的路径名限制不当，可能导致攻击者通过workflow_files输入中的目录遍历序列，将受控内容写入预期工作流包目录之外的任意位置。

Vulnerability Title
Path traversal and arbitrary file write in the workflow linters of aws-healthomics-mcp-server
Source: CVE Program / CVE List V5
Vulnerability Description
AWS HealthOmics is a HIPAA-eligible service that fully manages the compute, storage, and workflow engine infrastructure required to run bioinformatics analyses at scale for clinical diagnostics, drug discovery, and agricultural research. Improper limitation of a pathname to a restricted directory in the linting tools of the AWS HealthOmics MCP Server (aws-healthomics-mcp-server) before version 0.0.36 might allow an actor who can influence the MCP agent to write an actor-controlled content to arbitrary locations outside the intended workflow bundle directory, via directory traversal sequences in the workflow_files input. To remediate this issue, users should upgrade to version 0.0.36 or later.
