SKILL.md:34-38:bash # Install dependencies pip install playwright playwright-stealth playwright install chromiumEquivalent installation instructions appear in
references/SETUP.md:19-23:bash ### 2. Install Python dependencies ```bash pip install playwright playwright-stealth playwright install chromiumtext ### Technical Analysis The installation instructions retrieve mutable latest releases of `playwright`, `playwright-stealth`, their transitive dependencies, and a Chromium binary without a version lock file, exact version constraints, or package hashes. These dependencies execute with the privileges of the user installing or running the Skill. At runtime, they also interact with the persistent browser profile containing the authenticated Goodreads session. If a dependency release, dependency account, package registry response, or transitive package is compromised, attacker-controlled installation or import code could execute locally. No alternate package registry, obvious typosquatting, or intentionally malicious package was found. This is therefore a supply-chain hardening deficiency rather than evidence that the named dependencies are currently malicious. ### Attack Path 1. A threat actor compromises a dependency or one of its transitive dependencies, or publishes a malicious release through a compromised maintainer account. 2. A user follows the documented setup and runs the unpinned `pip install` command. 3. Package resolution selects the compromised release because no reviewed version or hash is enforced. 4. Malicious installation hooks or imported runtime code execute with the user’s privileges. 5. The malicious code can access files readable by that user, interact with the browser process, inspect the persistent Goodreads ...[truncated 676 chars]- Remediation

Remediation Suggestions
- Create a reviewed dependency lock file containing exact versions for all direct and transitive Python dependencies.
- Generate and enforce cryptographic package hashes, for example:
bash python3 -m pip install --require-hashes -r requirements.txt- Pin the Playwright package version so that the associated Chromium download is reproducible.
- Document the expected Chromium revision and verify downloaded browser artifacts through Playwright’s supported integrity mechanisms.
- Install dependencies inside a dedicated, non-privileged virtual environment.
- Avoid running
pipor Playwright installation commands withsudo. - Use automated dependency scanning and review updates before changing locked versions.
