Full Analysis
- [REMOTE_CODE_EXECUTION]: The skill frequently employs
chrome-devtools.evaluate_scriptto execute arbitrary JavaScript within the user's active browser context. This is used for data extraction and page interaction, but it could be leveraged to execute malicious logic if the script content is influenced by data retrieved from untrusted web pages. - [COMMAND_EXECUTION]: Instructions in
references/browser-recipes.mdandSKILL.mddirect the agent to useshell_commandwith native fetch tools likecurlandInvoke-WebRequestto perform raw HTML fetches and download web assets. - [PROMPT_INJECTION]: The skill possesses a broad surface for indirect prompt injection because it processes live web content such as DOM snapshots, console messages, and network request data. It lacks specific defense mechanisms against instructions embedded in these external sources.
- Ingestion points: Web data enters the agent's context through
take_snapshot,list_console_messages, andget_network_request(documented inreferences/session-playbook.md). - Boundary markers: No specific delimiters or "ignore embedded instructions" warnings are utilized when handling external web content.
- Capability inventory: The agent has access to sensitive tools including
shell_command,evaluate_script, andupload_file(documented inreferences/browser-recipes.md). - Sanitization: There is no evidence of input validation, escaping, or filtering of the content retrieved from processed pages.
- [DATA_EXFILTRATION]: The skill is designed to operate within the user's current authenticated browser session, granting it access to sensitive cookies and login states. When combined with the skill's ability to perform network operations via
shell_command, this creates a high-risk path for data exfiltration. Additionally, an automated security scan flagged the example URLhttps://xi-xu.meas appearing on a blacklist.
