- Unpinned Third-Party Dependencies Create a Supply-Chain Risk## Vulnerability Details **File Location**: `SKILL.md:52-57`; additional dependency instructions appear in `README.md:55-66` **Vulnerability Type**: Unpinned third-party package installation **Risk Level**: Medium ### Vulnerable Code ```bash pip install SpeechRecognition pyaudio pip install pipwin pipwin install pyaudio ``` ### Technical Analysis The installation instructions retrieve and install packages without specifying reviewed versions, package hashes, a lockfile, or an approved package index. The effective code installed by these commands can therefore change after the Skill has been audited. Python package installation can execute package build and installation logic under the privileges of the invoking user. If an upstream package, dependency, account, or package-index response is compromised, users following these instructions could install attacker-controlled code. No evidence indicates that the currently named packages are malicious. The vulnerability is the absence of dependency integrity and reproducibility controls. ### Attack Path 1. An attacker compromises a listed package, one of its transitive dependencies, or its package-index distribution channel. 2. The attacker publishes a malicious release under a version accepted by the unpinned installation command. 3. A user follows the documented installation instructions. 4. `pip` resolves the malicious release because no version or hash restrictions are present. 5. Malicious build or package code executes with the installing user's privileges. 6. The installed package can execute again when imported by the voice-chat scripts. ### Impact Assessment Successful exploitation can provide arbitrary code execution with the privileges of the user running `pip` or launching the application. Depending on those privileges, an attacker could access user files, environment variables, microphone data, network resources, and credentials available to that accou ...[truncated 113 chars]
- Remediation
- ## Remediation Suggestions - Pin every direct dependency to a reviewed version. - Generate a lockfile that also fixes transitive dependency versions. - Require package hashes, for example through a requirements file used with `pip --require-hashes`. - Install dependencies in a dedicated virtual environment with ordinary user privileges. - Use an explicitly configured, trusted package index. - Review package provenance and release signatures where available. - Add automated dependency vulnerability and integrity scanning. - Replace the installation instructions with a reproducible command such as: ```bash python -m pip install --require-hashes -r requirements.txt ```
