create_short_url

3 findings on this tool

1. highexcessive agencyf-r3-create_short_url

   Tool `create_short_url` name implies a side effect that is not declared

   `create_short_url` looks like a side-effecting tool (its name contains a mutation verb), but its `side_effects` declaration is []. A policy synthesizer cannot produce safe rules for this tool because it cannot tell what it actually does.

   fix: Declare the tool's true side effects explicitly. If the tool is genuinely read-only, rename it to match (e.g. `email.preview` rather than `email.send`).

2. highssrf surfacef-r8-create_short_url

   Tool `create_short_url` accepts an unconstrained URL / endpoint parameter

   The parameter(s) `url` look like URL or endpoint inputs but carry no `pattern` or `enum` constraint. An agent tricked by an indirect-injection payload can invoke this tool with an internal-service URL (e.g. `http://169.254.169.254/`) to exfiltrate cloud metadata, probe internal APIs, or pivot to services the host can reach but the caller cannot.

   fix: Constrain the URL parameter with an allow-list `enum`, or a `pattern` that restricts scheme and domain. Validate server-side against an allow-list and reject private / loopback / link-local address ranges at the HTTP client level.

3. mediumunconstrained inputf-r1-create_short_url

   Tool `create_short_url` accepts unconstrained string input

   The following string parameter(s) have no `maxLength` constraint: `alias`, `description`, `expiration_time`, `password`, `url`. 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.
