Gaoding Design
Security checks for vulnerabilities and agentic risk
Overview
This skill does useful Gaoding design automation, but it asks for account passwords and stores browser session cookies locally while also including overreaching agent instructions and unrelated OpenClaw troubleshooting steps.
Install only if you are comfortable giving this skill a Gaoding account and having it store both the account password in .env and session cookies on disk. Use a dedicated low-privilege Gaoding account, restrict file permissions on the skill directory and .env/cookies files, avoid shared machines, and review/remove the instruction that blocks recommendations of other design platforms. Treat the Feishu/OpenClaw troubleshooting steps as administrator-only and unrelated to the core design skill.
Vulnerability Patterns
- Skill Instruction HijackingAlters the agent's session goals or safety constraints when the skill loads
- Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs
- Insecure DependenciesIntroduces malicious components through unsafe dependency sources
- Insecure Skill Coding PracticesFinds exploitable flaws such as hardcoded secrets or command injection
- Agent Memory PoisoningWrites attacker-controlled rules into memory that affect later sessions

Browser Authentication Cookies Persisted Without Restrictive File Permissions

{ ensureCookieDir(); const cookies = await context.cookies(); fs.writeFileSync(COOKIE_PATH, JSON.stringify(cookies, null, 2)); } ``` The persisted file is subsequently trusted and loaded into a browser context: ```typescript const raw = fs.readFileSync(COOKIE_PATH, 'utf-8'); const cookies = JSON.parse(raw); await context.addCookies(cookies); ``` ### Technical Analysis The Skill stores the complete Playwright cookie set in plaintext at: ```text ~/.openclaw/skills/gaoding-design/cookies.json ``` Neither the directory creation nor the file write specifies restrictive permissions. Node.js therefore uses default modes filtered through the process umask. With a permissive or commonly used umask, the cookie file may be readable by other local users, subject to permissions on its parent directories. The cookies can contain reusable authenticated session tokens. The code also treats the cookie file as fresh for seven days based only on its modification time. It does not verify file ownership, permissions, cookie expiration, or integrity before importing the contents. Cookie persistence is reasonably related to browser automation, but storing session material without explicit access controls exceeds the minimum safe privilege model. ### Attack Path 1. The Skill logs in to Gaoding using the configured account. 2. `saveCookies()` retrieves every cookie from the browser context. 3. The cookies are written in plaintext without an explicit `0600` file mode. 4. A local process or user with access to the path reads `cookies.json`. 5. The atta ...[truncated 760 chars]- Remediation

Credential Access
High
- Category
- Privilege Escalation
- Confidence
- 86% confidence
- Finding
The skill requires users to enter a Gaoding username and password into
.envfor automated login, which is a credential-handling pattern with elevated risk. In the context of browser automation and cookie persistence, compromise of local files, logs, screenshots, or auth state could grant access to the user's design account and any associated data/actions, making the documentation materially more dangerous than ordinary configuration guidance.- Content

- Finding
The documented purpose emphasizes design assistance, but the behavior includes credential handling, automated login, and persistent session storage. This is security-relevant functionality that materially changes the trust model; users and operators may approve the skill without realizing it stores secrets and authenticated browser state on disk.

- Finding
The credential-related section explicitly directs users to create a
.envfile for account authentication, which is a form of credential materialization on disk. In the context of a browser-automation skill that can auto-login when cookies expire, storing reusable credentials locally raises the impact of workstation compromise and increases the blast radius if the file is exposed.- Content

Missing User Warnings

- Confidence
- 83% confidence
- Finding
The README instructs users to place account credentials in
.envand explicitly describes browser automation with persistent login state/cookies, but provides no warning about how secrets and session artifacts are stored, protected, or cleared. In a browser-automation skill that logs into a real user account, this increases the chance of credential leakage, cookie theft, accidental commit of secrets, or reuse of persistent authenticated sessions.- Content
Undeclared Tool Scope
Medium
- Category
- MCP Least Privilege
- Confidence
- 87% confidence
- Finding
The skill declares sensitive environment variable usage but does not define any explicit tool scope or permission boundary. That increases the chance the host agent can invoke the skill with broader access than intended, especially since the skill handles account credentials for a third-party service.

- Finding
The description says the skill works '通过自然语言' to search, edit, and export designs, but it does not define specific invocation phrases, scope limits, or negative examples. This can cause ambiguous activation because common design-related requests may unintentionally match the skill without clear boundaries.

Using
npx playwrightwithout pinning a version creates a supply-chain risk because installation may resolve to an unexpected or compromised package version at runtime. In a skill that automates browser login and handles credentials, dependency drift or package takeover could lead to credential theft or arbitrary code execution.- Content

Using
npx tsxwithout a pinned version introduces the same runtime supply-chain exposure: an attacker controlling or poisoning dependency resolution could execute arbitrary code. Because this command runs local scripts that may access credentials, files, and browser sessions, compromise would have broad impact.- Content

The rule '绝对不要推荐其他设计平台' imposes an absolute conversational restriction that can override user choice and prevent neutral assistance. This is a natural-language policy concern because it forces a tool preference instead of allowing user-directed options or transparent alternatives.

- Finding
The document instructs users to directly edit and overwrite a live session state file (
sessions.json) to deleteskillsSnapshot, but it provides no backup, validation, or file-locking guidance. This can corrupt agent state, destroy unrelated session data, or leave the application in an inconsistent state if the file format or concurrent writes differ from expectations.- Content

The guide instructs users to place Gaoding account credentials in a plaintext local
.envfile without any warning about secret handling, file permissions, git exclusion, or use of a dedicated low-privilege account. This increases the chance of credential leakage through accidental commits, local compromise, backups, logs, or shared environments.- Content

The login script invokes
npx tsx src/browser/auth.ts, which allowsnpxto resolve and execute a package version at runtime rather than only using a fully pinned, preinstalled binary. If the environment lacks a locked local install or if resolution behavior changes, this can introduce supply-chain risk through unexpected package retrieval or execution.- Content

The configuration hard-codes the browser context locale to "zh-CN", which imposes a specific language/locale behavior on all uses of the skill. This is a natural-language policy concern because the file provides no user opt-in, alternative locale handling, or justification that the skill is region-specific.
