Risk Level: SAFEPROMPT_INJECTIONDATA_EXFILTRATIONCOMMAND_EXECUTION
Full Analysis
- [Prompt Injection] (LOW): The skill is vulnerable to Indirect Prompt Injection (Category 8) because it ingests untrusted data from external websites and grants the agent significant browser control capabilities.
- Ingestion points: External web content loaded via
agent-browser openand analyzed viasnapshot. - Boundary markers: None present to distinguish between tool instructions and untrusted web content.
- Capability inventory: Full browser interaction (
click,fill,type), session management (state save/load), and data extraction (get text,screenshot). - Sanitization: No sanitization or filtering of the DOM/Accessibility tree is defined.
- [Data Exfiltration] (LOW): The
state saveandstate loadcommands allow the agent to read and write authentication session data (cookies, storage) to local files (e.g.,auth.json). If the agent is compromised by a malicious prompt, this sensitive data could be targeted for exfiltration. - [Command Execution] (SAFE): The skill defines a command-line interface for the
agent-browsertool. While it involves executing system commands, this behavior is restricted to the documented toolset and is standard for this skill's primary purpose.
