dbc

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

• Third-party content exposure detected (high risk: 0.90). This skill's SKILL.md explicitly instructs fetching and running remote install scripts from a public site (e.g., "curl -LsSf https://dbc.columnar.tech/install.sh | sh" and the PowerShell "irm https://dbc.columnar.tech/install.ps1 | iex"), so the agent would consume and execute untrusted third-party web content that can materially change behavior.

MEDIUM W012: Unverifiable external dependency detected (runtime URL that controls agent).

• Potentially malicious external URL detected (high risk: 1.00). The skill explicitly instructs users to run remote install scripts at runtime—curl -LsSf https://dbc.columnar.tech/install.sh | sh and irm https://dbc.columnar.tech/install.ps1 | iex—which fetch and execute remote code and are presented as required installation paths for the dbc dependency.
