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.

Affected products

• aws-healthomics-mcp-server: before 0.0.36 — fixed in 0.0.36

How to fix

Upgrade to a fixed version: aws-healthomics-mcp-server 0.0.36. Check the vendor advisory for mitigations.
