- Unpinned Third-Party Package Installation## Vulnerability Details **File Location**: `SKILL.md`, lines 94-96 **Vulnerability Type**: Unpinned dependency installation **Risk Level**: Medium **Vulnerable Code Snippet**: ```bash # Install pip install openai-whisper ``` ### Technical Analysis The documented installation command retrieves `openai-whisper` and its transitive dependencies from the active pip package index without specifying reviewed versions or verifying package hashes. The installed code can therefore change after the Skill has been audited. If an upstream release, transitive dependency, configured package index, or package distribution is compromised, pip may download and execute attacker-controlled installation logic. This is a supply-chain weakness rather than evidence that the currently named package is malicious. ### Attack Path 1. A user selects the local Whisper transcription option. 2. The Agent follows the installation instruction in `SKILL.md`. 3. Pip resolves mutable package and dependency versions from its configured index. 4. An attacker compromises an upstream release, a transitive dependency, or an index available through the user's pip configuration. 5. Pip downloads the compromised distribution. 6. Malicious installation or package code executes with the privileges of the account performing the installation. ### Impact Assessment Successful exploitation could allow arbitrary code execution under the installing user's privileges. The attacker could access files and environment variables available to that account, alter user-owned files, tamper with transcription output, or establish additional user-level compromise. System-wide impact would require the installation to be run with elevated privileges; the Skill does not itself instruct users to elevate privileges.
- Remediation
- ## Remediation Suggestions - Pin `openai-whisper` to a specifically reviewed version instead of resolving the latest available release. - Lock all transitive dependencies and require cryptographic hashes, such as through a hash-verified requirements file generated by a dependency-locking tool. - Install into a dedicated virtual environment with only user-level privileges. - Explicitly specify and document the trusted official package index, and prevent fallback to untrusted supplemental indexes. - Require explicit user confirmation before installing any package. - Periodically review and update the pinned dependency set after checking release provenance, vulnerability advisories, and package integrity. - Avoid running pip as an administrator or root user.
