Vulnerability Type: Supply-chain exposure through unpinned dependencies and dynamically downloaded browser components
Risk Level: Mediumbash # requests if ! $PYTHON -c "import requests" 2>/dev/null; then echo "[*] 安装 requests ..." $PYTHON -m pip install requests --quiet fi echo "[OK] requests" # playwright if ! $PYTHON -c "from playwright.sync_api import sync_playwright" 2>/dev/null; then echo "[*] 安装 playwright ..." $PYTHON -m pip install playwright --quiet echo "[*] 安装 Chromium (playwright) ..." $PYTHON -m playwright install chromium --with-deps 2>/dev/null || \ $PYTHON -m playwright install chromium 2>/dev/null fiTechnical Analysis
The documented entry script automatically installs
requests,playwright, Chromium, and potentially Chromium operating-system dependencies when they are absent. The Python package installations do not specify versions, hashes, a lockfile, or a fixed trusted package index. The Chromium artifact is also selected and downloaded dynamically.As a result, the source code reviewed in this audit does not fully determine which third-party code will be installed and executed. Package resolution is affected by the configured Python package index, mirrors, local pip configuration, and the package versions available when the script runs. If any relevant package repository, mirror, release, or artifact distribution channel is compromised, a malicious component could be supplied to the user.
The
--with-depsoption further expands the installation scope by permitting Playwright's installer to request operating-system dependencies. The exact privilege impact depends on the host configuration and the privileges under which the script is invoked.Attack Path

Remediation Suggestions
-
Move Python dependencies into a reviewed lockfile with exact versions and cryptographic hashes.
-
Install them with hash verification, for example:
bash python -m pip install --require-hashes -r requirements.txt -
Configure a fixed, trusted package index and prevent unexpected fallback to untrusted or environment-controlled mirrors.
-
Pin the Playwright version and its corresponding Chromium revision, and verify downloaded browser artifacts using trusted checksums or signatures.
-
Remove automatic dependency installation from the runtime entry point. Provide a separate, explicit setup procedure that requires user approval.
-
Avoid automatically invoking
playwright install --with-deps. Document required operating-system packages and let administrators install reviewed versions through the platform's package-management process. -
Run the Skill in an isolated virtual environment or container under a dedicated, unprivileged account.
-
Add dependency vulnerability and integrity checks to the release process, and update pinned versions only after review and testing.
