- Unpinned Dependencies Installed into the System Python Environment## Vulnerability Details **File Location**: `claw.json`, line 10 **Vulnerability Type**: Unpinned third-party dependencies and unsafe system-level package installation **Risk Level**: Medium ### Vulnerable Code ```json "commands": ["pip3 install edge-tts Pillow --break-system-packages || pip install edge-tts Pillow"], ``` ### Technical Analysis The installation command retrieves `edge-tts` and `Pillow` without fixed versions or package hashes. Consequently, the code installed during deployment can differ from the code assessed during this audit. If a dependency, transitive dependency, package index, or distribution account is compromised, a malicious release could be selected and installed. The primary command also uses `--break-system-packages`, bypassing protections intended to prevent `pip` from modifying an externally managed system Python environment. This can overwrite or introduce conflicts with operating-system-managed packages. The fallback command remains unpinned and does not isolate dependencies in a virtual environment. The reviewed evidence does not establish that the currently published dependencies are malicious. The vulnerability is the uncontrolled supply-chain and installation process. ### Attack Path 1. An attacker compromises a dependency or transitive dependency release, its publisher account, or the package source used by `pip`. 2. The attacker publishes a malicious version that satisfies the unconstrained dependency request. 3. A user installs the skill, causing `pip` to resolve and download that version. 4. Package installation hooks, imported modules, or runtime code execute on the host. 5. The malicious package acts with the privileges of the user or service account performing installation or running the skill. ### Impact Assessment Successful exploitation could permit arbitrary code execution with the privileges of the installer or runtime account. Depending on those privileges, an attacker could access that account's files ...[truncated 378 chars]
- Remediation
- ## Remediation Suggestions 1. Pin every direct dependency to an audited version, for example: ```text edge-tts==<reviewed-version> Pillow==<reviewed-version> ``` 2. Generate a lock file that includes all transitive dependencies and cryptographic hashes. Install with hash verification, such as: ```bash python3 -m pip install --require-hashes -r requirements.txt ``` 3. Install dependencies inside a dedicated virtual environment rather than the system Python environment: ```bash python3 -m venv .venv .venv/bin/python -m pip install --require-hashes -r requirements.txt ``` 4. Remove `--break-system-packages` and do not fall back to an unisolated, unpinned installation. 5. Configure an approved package index or internal artifact repository and enforce TLS certificate validation. 6. Scan and review dependency updates before modifying pinned versions, including transitive dependency and provenance checks. 7. Run installation and media generation under a non-privileged service account with restricted filesystem and network access.
