E006: Malicious code pattern detected in skill scripts

What this means

Detected high-risk code patterns in the skill content — including its prompts, tool definitions, and resources — such as data exfiltration, backdoors, remote code execution, credential theft, system compromise, supply chain attacks, and obfuscation techniques.

Why it was flagged

Malicious code pattern detected (high risk: 0.90). The skill exposes powerful, sensitive primitives (cookie export and CDP Network.getCookies, JS Runtime.evaluate, browser-use python arbitrary-statement execution, ability to connect/use a user's Chrome profile, cloud sessions and public tunnels, and REST passthrough) that can be deliberately abused for credential theft, data exfiltration, and remote access even though they are presented as legitimate features.

W007: Insecure credential handling detected in skill instructions

What this means

The skill handles credentials insecurely by requiring the agent to include secret values verbatim in its generated output. This exposes credentials in the agent’s context and conversation history, creating a risk of data exfiltration.

Why it was flagged

Insecure credential handling detected (high risk: 1.00). The prompt includes commands that explicitly pass API keys and passwords as command-line arguments (e.g., "browser-use cloud login <api-key>" and example chains with "password"), which would require the agent to include secret values verbatim in generated commands or outputs, creating an exfiltration risk.

Medium

W011: Third-party content exposure detected (indirect prompt injection risk)

What this means

The skill exposes the agent to untrusted, user-generated content from public third-party sources, creating a risk of indirect prompt injection. This includes browsing arbitrary URLs, reading social media posts or forum comments, and analyzing content from unknown websites.

Why it was flagged

Third-party content exposure detected (high risk: 0.85). The skill’s runtime workflow includes navigating to a user-supplied URL (`browser-use open <url>`), after which the agent reads page content via `browser-use state`/`browser-use get text`/`browser-use get html` (browser-extracted free text from outsider-authored web pages), creating an indirect prompt-injection path into the LLM context.
