- Unpinned Third-Party Package and Browser Component Installation## Vulnerability Details **File Location**: `SKILL.md`, lines 19–20 **Vulnerability Type**: Supply-chain exposure through unpinned executable dependencies **Risk Level**: Medium **Complete Code Snippet**: ```bash pip install "scrapling[all]" scrapling install ``` ### Technical Analysis The documented setup process installs the latest available release of `scrapling` with all optional dependencies and then invokes the package's installation command to download additional browser components. Neither exact package versions nor artifact hashes are specified. Consequently, the code and browser artifacts installed at setup time can differ from those present when this skill was audited. The broad `[all]` extra also increases the number of transitive dependencies and therefore expands the supply-chain attack surface. The audit found no evidence that the currently referenced package is malicious; the issue is the absence of reproducible, integrity-verified dependency controls. ### Attack Path 1. An attacker compromises the upstream package, one of its transitive dependencies, its distribution account, or a browser-component distribution channel. 2. The attacker publishes or substitutes a malicious artifact under a version accepted by the unrestricted installation commands. 3. A user follows the documented Quick Start and runs `pip install "scrapling[all]"`. 4. The malicious package or dependency is installed and may execute code through package installation behavior or when imported by `scrapling_tool.py`. 5. The user runs `scrapling install`, which obtains additional unpinned components and may execute package-controlled installation logic. 6. Attacker-controlled code runs with the privileges of the user performing installation or invoking the skill. ### Impact Assessment Successful supply-chain compromise could permit arbitrary code execution under the installing user's account. This could expose files, environment variab ...[truncated 395 chars]
- Remediation
- ## Remediation Suggestions 1. Pin `scrapling` and every transitive Python dependency to reviewed, exact versions in a lockfile. 2. Require cryptographic hashes for downloaded Python distributions, such as by using `pip install --require-hashes -r requirements.txt`. 3. Pin browser components to reviewed versions and verify their checksums or signatures before installation. 4. Document the trusted package indexes and artifact origins; disable untrusted or supplemental indexes to reduce dependency-confusion risk. 5. Install dependencies inside an isolated virtual environment or container under a dedicated, unprivileged account. 6. Avoid running package or browser installation commands as root. 7. Periodically scan the lockfile and downloaded artifacts for known vulnerabilities, and review all version updates before changing the pins. 8. Consider replacing the broad `[all]` extra with only the features required by the selected scraping modes, reducing the transitive attack surface.
