1. mediumunconstrained inputf-r1-firecrawl_interact_stop

   Tool `firecrawl_interact_stop` accepts unconstrained string input

   The following string parameter(s) have no `maxLength` constraint: `scrapeId`. 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.

2. mediumindirect injectionf-r6-firecrawl_interact_stop

   Tool `firecrawl_interact_stop` fetches external web content -- indirect-injection surface

   Description: " Stop an interact session for a scraped page. Call this when you are done interacting to free resources. **Usage Example:** ```json { "name": "firecrawl_interact_stop", "arguments": { "scrapeId": "scrape-id-here" } } ``` **Returns:** Success confirmation. " -- this tool pulls externally-controlled content into the agent's context window, the canonical indirect-injection vector. Even when the user supplies the URL, content at that URL can carry hostile instructions.

   fix: Sandbox the fetched content: strip prompts before forwarding to the model, constrain to an allow-list of domains, and route through capframe-guard with a `domain in [...]` caveat.
