MEDIUM W011: Third-party content exposure detected (indirect prompt injection risk).

• Third-party content exposure detected (high risk: 0.80). The binary-deployment gate (references/binary-deployment-gate.md) includes a remediation that runs a remote install script via "bash <(curl -fsSL https://raw.githubusercontent.com/.../install.sh)", which requires fetching and potentially executing public GitHub-hosted (user-generated) content as part of the workflow, exposing the agent to untrusted third-party instructions.
