- Unpinned Third-Party Dependencies Without Integrity Verification## Vulnerability Details **File Location**: `SKILL.md`, line 12 **Vulnerability Type**: Uncontrolled third-party dependency resolution **Risk Level**: Medium **Vulnerable Code**: ```bash pip install mss pytesseract pillow pyautogui opencv-python numpy ``` ### Technical Analysis The documented installation command installs six third-party packages without fixed versions or cryptographic hash verification. Consequently, the exact code installed is determined by the package index at installation time rather than by a reviewed and reproducible dependency manifest. Package installation may execute package build or installation logic, and imported dependencies execute with the privileges of the user running the Skill. A compromised package release, compromised transitive dependency, unsafe package-index configuration, or malicious package-index mirror could therefore introduce code that was not present during this audit. No evidence was found that the named packages are currently malicious. The vulnerability is the absence of dependency pinning and integrity controls, which creates an avoidable supply-chain trust boundary. ### Attack Path 1. An attacker compromises a listed package, one of its transitive dependencies, or a package index used by the victim. 2. The attacker publishes a malicious release that is compatible with the unconstrained installation request. 3. A user follows the installation instructions in `SKILL.md`. 4. `pip` resolves and downloads the attacker-controlled release because no reviewed version or hash is required. 5. Malicious code executes during installation or when the dependency is imported by the Skill. ### Impact Assessment Successful exploitation could execute arbitrary code with the privileges of the user installing or running the Skill. Depending on those privileges, the attacker could access local files and screen contents, modify user data, steal credentials availa ...[truncated 284 chars]
- Remediation
- ## Remediation Suggestions 1. Replace the unconstrained installation command with dependencies pinned to exact, reviewed versions. 2. Generate a lock file containing cryptographic hashes for all direct and transitive dependencies. 3. Install dependencies using hash enforcement, such as: ```bash pip install --require-hashes -r requirements.txt ``` 4. Configure installation to use an explicitly trusted package index and disallow unexpected supplemental indexes. 5. Review and update pinned dependencies through a controlled process that includes vulnerability scanning and package provenance verification. 6. Perform installation in an isolated virtual environment under a non-administrative account. 7. Consider producing signed, reproducible deployment artifacts so users do not resolve dependencies dynamically at installation time.
