Risk Level: SAFEPROMPT_INJECTION
Full Analysis
- [PROMPT_INJECTION]: The skill is susceptible to indirect prompt injection because it processes untrusted data from external web sources. This occurs when the agent navigates to or scrapes a website containing hidden instructions designed to manipulate its subsequent actions.
- Ingestion points: Data enters the agent's context through the
open,scrape, andsnapshotcommands, which fetch content from arbitrary URLs. - Boundary markers: The skill instructions do not specify the use of delimiters or provide 'ignore embedded instructions' warnings for the agent when handling scraped data.
- Capability inventory: The skill allows for significant browser interaction (clicks, form fills), remote JavaScript execution via the
evalcommand, and local file writing using the--outputflag. - Sanitization: There is no evidence of sanitization or filtering of the content retrieved from external sites before it is presented to the agent.
