- Unnecessary Unpinned Third-Party Dependency Creates Supply-Chain Code-Execution Risk## Vulnerability Details **File Location**: `requirements.txt:1` **Related Instruction**: `SKILL.md:232-236` **Vulnerability Type**: Unnecessary and unpinned third-party dependency **Risk Level**: Medium ### Complete Code Snippet `requirements.txt:1`: ```text main ``` `SKILL.md:232-236`: ```markdown ## Prerequisites ```text # Python dependencies pip install -r requirements.txt ``` ``` ### Technical Analysis The primary requirements file declares the generic, unpinned package `main`, and the skill documentation instructs users or Agents to install it with `pip`. This dependency is unnecessary for the declared functionality. `scripts/main.py` imports only Python standard-library modules, while `references/requirements.txt:13-20` explicitly states that no external dependencies or installation are required. Installing a package can execute package-controlled build or installation logic. Because `main` is not version-pinned or hash-verified, the installed artifact depends on the configured package index and its current state. A compromised, substituted, or otherwise unexpected distribution could therefore execute code with the privileges of the user running `pip`. This behavior exceeds the minimum privileges needed for a local, standard-library-only case generator. ### Attack Path 1. A user or automated Agent follows the prerequisite instructions in `SKILL.md`. 2. The Agent runs: ```bash pip install -r requirements.txt ``` 3. `pip` resolves the unpinned package named `main` from the configured package index. 4. The selected distribution performs package-controlled build or installation operations. 5. If that distribution is malicious or compromised, its code executes with the installing process's permissions. 6. The package could then access data and resources available to that user, including the project workspace and user-level files. This audit did not establish that the currently resolved package is malicious; the vulnerability is the u ...[truncated 1452 chars]
- Remediation
- ## Remediation Suggestions 1. Remove the unnecessary package declaration from `requirements.txt`: ```text # No external dependencies required. ``` Alternatively, remove the file if the packaging system does not require it. 2. Replace the installation instructions in `SKILL.md` with: ```markdown ## Prerequisites Python 3.8 or later is required. No external Python packages are needed. ``` 3. If third-party dependencies become necessary in the future: - Use the exact verified package name. - Pin each dependency to a reviewed version. - Require cryptographic hashes, such as through `pip install --require-hashes`. - Install only from an approved package index. - Review source distributions and build-system dependencies. - Run installation and execution in an isolated, least-privileged environment. 4. Add automated dependency checks that fail when undeclared or unnecessary external dependencies are introduced. 5. Correct `references/topics.json` by converting invalid expressions to valid JSON values, such as strings or numeric arrays, even though this issue is not directly exploitable in the current implementation.
