SKILL.md:125-127
Vulnerability Type: Supply-chain exposure through unpinned dependencies
Risk Level: Mediumbash ### Environment Setup ```bash # Dependencies pip install requests beautifulsoup4text ### Technical Analysis The setup instructions install `requests` and `beautifulsoup4` without version constraints, package hashes, a lockfile, or an explicitly trusted package index. Consequently, the artifacts installed can change between executions even though the reviewed Skill remains unchanged. Although both package names are established packages and the file does not intentionally reference a malicious source, an upstream account compromise, malicious release, package-index compromise, or unexpected incompatible release could cause unreviewed code to enter the runtime environment. Python packages and their transitive dependencies can execute package-controlled code during installation or later when imported by an implementation. The project does not include the referenced implementation scripts, so it is not possible to verify how these dependencies would be imported or used. ### Attack Path 1. An attacker compromises an upstream dependency release, one of its transitive dependencies, or the package distribution channel. 2. The attacker publishes a malicious version that still satisfies the unconstrained installation command. 3. A user or agent follows the documented setup procedure and runs `pip install requests beautifulsoup4`. 4. Pip resolves and installs the attacker-controlled artifact because no reviewed version or hash is enforced. 5. Malicious package code executes during installation or when the package is subsequently imported. ### Impact Assessment Exploitation could execute code with the privileges of the user running pip or the eventual Skill implementation. Depending on those privileges, an attacker could read or modify user-accessible ...[truncated 266 chars]- Remediation

Remediation Suggestions
- Pin every direct dependency to an explicitly reviewed version.
- Pin transitive dependencies through a generated lockfile.
- Require cryptographic hashes, such as with a hash-locked
requirements.txtandpip install --require-hashes. - Configure pip to use an explicitly trusted package index and disallow unexpected extra indexes.
- Install dependencies in an isolated virtual environment under a non-privileged account.
- Add automated dependency vulnerability and integrity scanning.
- Document a controlled update process in which new dependency versions are reviewed and lockfiles are regenerated.
