  message: >-
    User-controllable argument $DATAVAL to $METHOD passed to Axios
    via internal handler $INNERFUNC.
    This could be a server-side request forgery. A user could call
    a restricted API or leak internal headers to an unauthorized party.
    Validate your user arguments against an allowlist of known URLs, or
    consider refactoring so that user-controlled data is not necessary.
