- Unpinned Third-Party Dependencies## Vulnerability Details **File Location**: `requirements.txt`, lines 1–4 **Vulnerability Type**: Unpinned third-party dependencies **Risk Level**: Medium ### Vulnerable Code ```text python-dotenv httpx[socks] google-genai Pillow ``` The installation instruction appears in `SKILL.md`, line 16: ```bash python3 -m pip install -r ${CLAUDE_PLUGIN_ROOT}/skills/nanobanana-skill/requirements.txt ``` ### Technical Analysis All dependencies are specified without exact versions or integrity hashes. Consequently, repeated installations can resolve to different package versions over time. A compromised, malicious, or unexpectedly incompatible future release could be installed without a source change or additional review. Because Python packages may execute code during installation and are subsequently imported into the application, compromise of a resolved dependency can result in code execution under the account installing or running the skill. The unpinned `httpx[socks]` dependency is not directly imported by `nanobanana.py`, which increases the dependency surface unless it is required transitively by another package. This finding does not establish that any listed package is currently malicious. It identifies insufficient controls against dependency drift and upstream supply-chain compromise. ### Attack Path 1. An attacker compromises an upstream dependency release, maintainer account, or relevant package distribution path. 2. The attacker publishes a malicious version satisfying the unrestricted dependency specification. 3. A user follows the documented installation command. 4. `pip` resolves and installs the attacker-controlled version because no reviewed version or package hash is enforced. 5. Malicious code executes during package installation, import, or normal library use with the privileges of the installing or running user. ### Impact Assessment Successful exploitation could provide arbitrary code e ...[truncated 533 chars]
- Remediation
- ## Remediation Suggestions 1. Pin every direct dependency to a reviewed exact version, using `==`. 2. Generate and enforce a lock file containing cryptographic hashes, such as a hash-locked requirements file produced through `pip-tools`. 3. Install dependencies with hash enforcement: ```bash python3 -m pip install --require-hashes -r requirements.txt ``` 4. Review and pin transitive dependencies as well as direct dependencies. 5. Remove `httpx[socks]` if dependency analysis confirms it is unnecessary. If SOCKS support is not required, avoid enabling the extra. 6. Use a trusted package index or controlled internal mirror and restrict fallback to unapproved indexes. 7. Periodically scan dependencies for known vulnerabilities and update pins only after compatibility and security review. 8. Perform installation in an isolated virtual environment or container with least privilege, and avoid installing packages as an administrator or root user.
