- Unpinned Third-Party Dependencies Permit Unreviewed Package Installation<![CDATA[ ## Vulnerability Details **File Location**: `requirements.txt:6-15` **Vulnerability Type**: Unbounded dependency versions without integrity hashes **Risk Level**: Medium ### Vulnerable Code ```text openai>=1.30.0 anthropic>=0.28.0 # ─── Image Generation (optional) ──────────────────────────────────── stability-sdk>=0.8.0 # Stable Diffusion XL — optional fallback # ─── Utilities ────────────────────────────────────────────────────── python-dotenv>=1.0.0 # .env environment variable loading pydantic>=2.0.0 # Data validation & serialization tencent-cloud-sdk-python>=0.1.0 # Tencent Hunyuan API — optional China image model ``` ### Technical Analysis Every dependency is specified using an open-ended minimum version constraint. There are no exact version pins, upper bounds, lockfile entries, or package hashes. Consequently, a future installation may resolve to package versions that were never reviewed with this project. Python packages can execute code during installation, import, or ordinary runtime use. If an allowed future release or its distribution infrastructure is compromised, installing this requirements file could introduce attacker-controlled code. The submitted artifact also contains no Python implementation that directly demonstrates a need for these dependencies, increasing the avoidable supply-chain attack surface. This finding does not establish that any currently named package or release is malicious. The vulnerability is the absence of deterministic version and integrity controls. ### Attack Path 1. A developer or deployment service runs `pip install -r requirements.txt`. 2. The package resolver queries the configured package index and selects any release satisfying each `>=` constraint. 3. A compromised or malicious future release satisfies the unrestricted constraint and is downloaded without hash verification. 4. Attacker-controlled package code executes during installation, import, or subsequen ...[truncated 723 chars]
- Remediation
- <![CDATA[ ## Remediation Suggestions 1. Remove dependencies that are not required by executable code shipped with the project. 2. Pin every required direct dependency to an exact, reviewed version using `==`. 3. Generate and commit a lockfile that includes resolved transitive dependencies. 4. Require package integrity hashes, for example through `pip-compile --generate-hashes` and `pip install --require-hashes`. 5. Install packages only from approved HTTPS indexes, and disable untrusted supplemental indexes. 6. Use automated dependency vulnerability and provenance scanning in CI. 7. Review and deliberately update locked dependencies on a controlled schedule rather than resolving arbitrary new releases during deployment. 8. Perform installation and execution in an isolated, least-privileged environment without unnecessary credentials or host filesystem access. ]]>
