- Unbounded Third-Party Dependency Versions## Vulnerability Details **File Location**: `requirements.txt:1-3` **Additional Locations**: `SKILL.md:54`, `SKILL.md:82` **Vulnerability Type**: Unrestricted dependency resolution without version locking or integrity verification **Risk Level**: Low ### Vulnerable Code ```text pandas>=2.0.0 openpyxl>=3.0.0 pdfplumber>=0.10.0 ``` The installation instructions in `SKILL.md` also install dependencies without version or integrity controls: ```bash pip install pandas openpyxl ``` ```bash pip install pdfplumber ``` ### Technical Analysis Each dependency has only a minimum version constraint and no upper bound, exact pin, lockfile, or cryptographic hash. Consequently, package installation may resolve to any future version published under these package names. The listed packages are recognizable PyPI projects; no evidence of typosquatting, dependency confusion, or an actively malicious release was identified. The risk is nevertheless present at the supply-chain boundary because the installed code can differ from the versions covered by this audit. If a package publisher account, distribution infrastructure, or future release is compromised, installation or import of the resolved package could execute attacker-controlled code. ### Attack Path 1. An attacker compromises a dependency publisher account or the relevant package distribution process. 2. The attacker publishes a malicious release whose version satisfies the unrestricted minimum-version constraint. 3. A user follows the documented installation instructions or installs `requirements.txt`. 4. The package resolver selects the malicious release because no exact version or hash is required. 5. Attacker-controlled package code executes during installation or when the extraction scripts import the affected dependency. This path requires an external supply-chain compromise; the audited repository does not itself retrieve an untrusted custom pac ...[truncated 505 chars]
- Remediation
- ## Remediation Suggestions 1. Pin each direct dependency to a reviewed exact version rather than using unrestricted minimum versions. 2. Generate and commit a reproducible lockfile that includes transitive dependencies. 3. Record cryptographic hashes and install with hash verification, such as: ```bash pip install --require-hashes -r requirements.txt ``` 4. Update `SKILL.md` so its installation commands reference the reviewed dependency manifest rather than installing unconstrained packages directly. 5. Perform dependency updates through a controlled review process that includes vulnerability scanning, changelog review, and testing. 6. Install and run the Skill in a least-privileged, isolated environment with restricted filesystem and network access.
