Summary

A directory traversal vulnerability was found in the linting tools of the AWS HealthOmics MCP Server (aws-healthomics-mcp-server) before version 0.0.36. An actor who can influence the MCP agent may write actor-controlled content to arbitrary locations outside the intended workflow bundle directory by using directory traversal sequences in the workflow_files input.

Risk Assessment

The risk involves overwriting or placing malicious files in sensitive filesystem locations, potentially leading to data integrity compromise, unauthorized code execution, or privilege escalation within the AWS HealthOmics environment.

Recommendation

Immediately upgrade the AWS HealthOmics MCP Server to version 0.0.36 or later, which contains the fix for the directory traversal vulnerability.

Original NVD description (English source)

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.
