- Unpinned Third-Party Dependency Allows Unreviewed Package Updates<![CDATA[ ## Vulnerability Details **File Location**: `requirements.txt:1` **Vulnerability Type**: `T08: Insecure Dependencies` **Risk Level**: Medium ### Vulnerable Code ```text gql[websockets]>=3.5.0 ``` The installation instructions in `SKILL.md:52-56` repeat the same unpinned installation pattern: ```bash pip install 'gql[websockets]' ``` ### Technical Analysis The requirement specifies only a minimum version and does not impose an upper bound, lock transitive dependencies, or verify package hashes. Consequently, future versions of `gql` and its WebSocket-related dependencies can be installed automatically without having been reviewed as part of this audit. This does not establish that the current package is malicious. The security issue is that the effective code installed by users can change after the skill has been reviewed. If an allowed future release or one of its transitive dependencies is compromised, malicious code could execute during package installation, import, or normal use. ### Attack Path 1. An attacker compromises the publishing account, build process, or distribution channel of `gql` or an allowed transitive dependency. 2. The attacker publishes a malicious version satisfying `>=3.5.0`. 3. A user follows the documented installation command or installs from `requirements.txt`. 4. `pip` resolves and downloads the malicious version because no exact version or hash is required. 5. Attacker-controlled code executes during installation, module import, or WebSocket client initialization. ### Impact Assessment Successful exploitation would execute code with the privileges of the user installing or running the skill. Depending on those privileges and the malicious package payload, this could expose environment variables—including `BITQUERY_API_KEY`—read or alter user-accessible files, make arbitrary network requests, or modify the Python environment. The project itself does not request elevated privileges, so the direct scope is limited ...[truncated 152 chars]
- Remediation
- <![CDATA[ ## Remediation Suggestions 1. Pin `gql` to a specific, reviewed version rather than using an open-ended lower bound. 2. Generate and commit a lock file that pins every transitive dependency. 3. Use package hashes and install with `pip --require-hashes` so altered distributions are rejected. 4. Review dependency updates before changing the lock file, including release notes, ownership changes, and vulnerability advisories. 5. Install dependencies in an isolated virtual environment under a non-privileged account. 6. Keep the installation instructions in `SKILL.md` consistent with the locked dependency process rather than recommending an unconstrained `pip install`. A hardened requirements entry should use a reviewed exact version, with hashes maintained by a lock-generation tool: ```text gql[websockets]==<reviewed-version> \ --hash=sha256:<verified-distribution-hash> ``` ]]>
