Full Analysis
- [EXTERNAL_DOWNLOADS]: The skill requires the installation of
browser-act-cli==1.1.0using theuvtool. The documentation explicitly states that the PyPI release consists of platform-specific binary wheels without a source distribution, which prevents independent security inspection of the underlying code. - [COMMAND_EXECUTION]: The agent is instructed to run the
browser-actCLI to perform browser tasks. The skill relies on the local--helpoutput of this external tool to determine available command syntax and capabilities. - [DATA_EXFILTRATION]: The CLI enables analytics and exception reporting by default, transmitting data to the vendor's infrastructure. Furthermore, features such as
solve-captchaandremote-assisttransmit challenge materials and browser session control to the vendor. - [PROMPT_INJECTION]: The skill is vulnerable to indirect prompt injection as it ingests untrusted data from the web.
- Ingestion points: Navigation to external URLs, DOM extraction, and network capture.
- Boundary markers: The skill warns the agent not to follow provider-served runtime guides but lacks specific delimiters or markers to separate web content from agent instructions.
- Capability inventory: The tool can perform clicks, form inputs, file uploads, and state-changing actions on remote websites.
- Sanitization: No sanitization or filtering of extracted content is specified before the agent processes it.
- [REMOTE_CODE_EXECUTION]: The skill automates the execution of JavaScript within a browser environment to render pages and interact with web elements, which represents a controlled form of code execution on remote content.
