CVE-2026-15415
Path traversal and arbitrary file write in the workflow linters of aws-healthomics-mcp-server
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.
