- Unpinned Playwright Dependency Permits Unreviewed Supply-Chain Updates## Vulnerability Details **File Location**: `requirements.txt:1` **Vulnerability Type**: Unpinned third-party dependency without integrity verification **Risk Level**: Medium ### Vulnerable Code ```text playwright>=1.40.0 ``` The documented installation workflow in `SKILL.md:78-81` consumes this requirement directly: ```bash cd {baseDir} && rm -rf .venv && python3 -m venv .venv && .venv/bin/pip install -r requirements.txt ``` ### Technical Analysis The `>=1.40.0` constraint permits pip to install any current or future Playwright release satisfying the lower bound. The project provides neither an exact version lock nor package hashes, so the installed dependency can change without corresponding source review. This creates a supply-chain risk: a compromised upstream release, compromised package-distribution account, or maliciously altered package artifact could be selected during a future environment rebuild. Although the package name is legitimate and there is no evidence that the current Playwright package is malicious, the dependency policy does not ensure reproducible or integrity-verified installations. The consequence is particularly relevant because both chatbot scripts import Playwright and connect it to an authenticated, persistent Chrome profile. Imported dependency code executes with the invoking user's OS privileges and participates in browser automation. ### Attack Path 1. An attacker compromises a future compatible Playwright release or its distribution channel. 2. A user follows the documented virtual-environment rebuild procedure. 3. Pip resolves `playwright>=1.40.0` to the compromised release because no exact version or hash is enforced. 4. The malicious package is installed into the Skill's virtual environment. 5. The user invokes `ask_chatgpt.py` or `ask_gemini.py`, causing Python to import and execute the compromised dependency. 6. The dependency executes with the user's privileges and may interact with the browser context exposed th ...[truncated 726 chars]
- Remediation
- ## Remediation Suggestions 1. Replace the lower-bound requirement with an exact, reviewed version: ```text playwright==<audited-version> ``` 2. Generate a reproducible lockfile that pins all transitive dependencies. 3. Record package hashes and install with pip's hash verification, such as `pip install --require-hashes`. 4. Update dependencies through a controlled review process that includes vulnerability scanning, release-note review, and tests before changing the lockfile. 5. Use a trusted package index configured explicitly for deployment, and prevent fallback to untrusted or unintended indexes. 6. Run the Skill under a least-privileged account and use a dedicated browser profile containing only the sessions required for this Skill.
