2 findings on this tool

  1. highexcessive agencyf-r4-aws___search_documentation

    Tool `aws___search_documentation` accepts an unbounded monetary / quota value

    The numeric parameter(s) `limit` have a money/quota-shaped name but no `maximum` constraint. An LLM tricked by indirect-injection can call the tool with arbitrarily large values.

    fix: Add a `maximum` (and ideally `minimum`) to each money/quota numeric, OR enforce the cap via a capframe-bind `--limit` caveat at the agent boundary.

  2. mediumunconstrained inputf-r1-aws___search_documentation

    Tool `aws___search_documentation` accepts unconstrained string input

    The following string parameter(s) have no `maxLength` constraint: `search_phrase`. Unbounded strings let an attacker stuff arbitrary payloads through the tool, including indirect-injection content.

    fix: Add a `maxLength` to each string property, or constrain with an `enum` or `pattern`. Most legitimate tool inputs fit under a few hundred bytes.
