- Unnecessary and Unpinned Third-Party Dependencies## Vulnerability Details **File Location**: `requirements.txt`, lines 1–2 **Vulnerability Type**: Unnecessary unpinned dependencies and avoidable supply-chain exposure **Risk Level**: Medium **Complete Code Snippet**: ```text dataclasses enum ``` ### Technical Analysis The project declares `dataclasses` and `enum` as external dependencies without exact version constraints or cryptographic hashes. The project documentation requires Python 3.7 or later, where both `dataclasses` and `enum` are already available from the Python standard library. Consequently, these package-index dependencies are unnecessary. Installing them causes a package manager to resolve mutable third-party distributions whose contents are not controlled by this repository. Because neither versions nor hashes are specified, a later installation may retrieve different artifacts from those reviewed during this audit. This finding does not establish that the currently published packages are malicious. It identifies an avoidable supply-chain trust boundary that could become exploitable if a package release, package-index account, mirror, or dependency-resolution source were compromised. ### Attack Path 1. A user or automated deployment process executes `pip install -r requirements.txt`. 2. The package manager queries its configured package index or mirror for `dataclasses` and `enum`. 3. Because no versions or hashes are pinned, the resolver accepts matching mutable distributions selected at installation time. 4. If an accepted distribution has been compromised or substituted, attacker-controlled package content enters the Python environment. 5. Malicious package behavior could then run during installation or when the package is imported by this or another process in the same environment. ### Impact Assessment Successful exploitation could execute code with the privileges of the account performing package installation or running the affected Python ...[truncated 379 chars]
- Remediation
- ## Remediation Suggestions 1. Remove both dependency declarations because Python 3.7 and later provide the required modules through the standard library. 2. Delete `requirements.txt` if the project has no external runtime dependencies, or leave it explicitly empty with a clarifying comment. 3. If third-party dependencies are added later, pin exact versions and use cryptographic hashes, such as with `pip install --require-hashes`. 4. Generate and review a reproducible lock file through an approved dependency-management workflow. 5. Restrict installations to a trusted package index or internal mirror and incorporate dependency scanning into CI. 6. Install dependencies in an isolated, least-privileged virtual environment or build container.
