Bulletin ID: 2026-060-AWS Scope: AWS Content Type: Important (requires attention) / Informational Publication Date: 07/17/2026 12:45 PM PDT 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. We identified CVE-2026-15415, where 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. Impacted versions: aws-healthomics-mcp-server
