- Unpinned Third-Party Dependencies Create Supply-Chain Exposure<![CDATA[ ## Vulnerability Details **File Location**: `scripts/requirements.txt:1-2` **Vulnerability Type**: Unpinned dependencies **Risk Level**: Medium ### Vulnerable Code ```text fastapi-poe requests ``` ### Technical Analysis The project instructs users to install dependencies from this requirements file, but neither dependency has a fixed version or an integrity hash. Consequently, installation resolves to whichever compatible release the package index serves at that time. This prevents reproducible dependency resolution and expands the trust boundary to future package releases. If a dependency account, release process, package index, or dependency tree is compromised, installation could introduce attacker-controlled code without any change to this Skill's reviewed source. No evidence indicates that the currently named packages are malicious. The vulnerability is the absence of version and integrity controls, rather than confirmed malicious package content. ### Attack Path 1. An attacker compromises a dependency maintainer account, package release process, package-index response, or transitive dependency. 2. The attacker publishes or causes resolution to a malicious version of `fastapi-poe` or `requests`. 3. A user follows the documented installation command: ```bash pip install -r scripts/requirements.txt ``` 4. Because no version or hash is enforced, `pip` may download the malicious release. 5. Malicious package code executes during installation or when the Skill imports and uses the dependency. ### Impact Assessment Attacker-controlled dependency code would generally execute with the privileges of the user installing or invoking the Skill. Depending on that user's access, this could expose Poe API credentials, user messages, explicitly uploaded files, environment variables, local files accessible to the process, and network access. It could also alter responses or perform other actions available to the current operating-system accoun ...[truncated 6 chars]
- Remediation
- <![CDATA[ ## Remediation Suggestions 1. Pin every direct dependency to a reviewed version, for example: ```text fastapi-poe==<reviewed-version> requests==<reviewed-version> ``` 2. Generate and retain a lock file that includes resolved transitive dependencies. 3. Record cryptographic hashes and install with `pip --require-hashes`. 4. Use a controlled package index or approved dependency mirror where practical. 5. Add automated vulnerability and dependency-update scanning. 6. Review dependency changes before updating pins, including transitive dependency changes and package provenance. ]]>
