- Unpinned Third-Party Dependencies Installed Without Integrity Verification## Vulnerability Details **File Location**: `SKILL.md:21-22`; `README.md:32-33` **Vulnerability Type**: T08: Insecure Dependencies **Risk Level**: Medium ### Vulnerable Code `SKILL.md:21-22`: ```bash pip install mss pyautogui Pillow pip install winrt ``` `README.md:32-33`: ```bash pip install mss pyautogui Pillow pip install winrt ``` ### Technical Analysis The installation instructions retrieve mutable third-party packages without pinning reviewed versions or verifying package hashes. The project also lacks a dependency lock file or requirements file that records exact versions and expected artifact digests. Consequently, different package releases may be installed at different times. If a dependency release or the configured package index is compromised, installation hooks or imported package code could execute attacker-controlled code. This is especially relevant because `mss` and `pyautogui` are used to access screen and pointer information. The reviewed instructions use conventional package names and do not specify an untrusted package source. Therefore, this finding represents supply-chain exposure rather than evidence that any listed package is currently malicious. ### Attack Path 1. An attacker compromises a listed package, its publisher account, its distribution artifact, or the package index used by the victim. 2. The attacker publishes or substitutes a malicious package release under a dependency name used by the project. 3. A user follows the documented unpinned `pip install` commands. 4. Package installation hooks or malicious code loaded during subsequent imports execute with the privileges of the Python or `pip` process. 5. The malicious dependency accesses user-level resources and may capture or disclose screen content, files, environment data, or other information available to that process. ### Impact Assessment Exploitation could provide arbitrary code execution with the privilege ...[truncated 465 chars]
- Remediation
- ## Remediation Suggestions 1. Create a reviewed `requirements.txt` or equivalent lock file containing exact dependency versions. 2. Record SHA-256 hashes for every permitted distribution artifact and install with `pip install --require-hashes -r requirements.txt`. 3. Explicitly document the trusted Python package index and prohibit fallback to arbitrary or user-controlled indexes. 4. Review package ownership, release history, transitive dependencies, and installation behavior before updating pinned versions. 5. Perform dependency updates through a controlled review process with vulnerability scanning and tests. 6. Recommend installation inside a dedicated virtual environment under a non-administrative account. 7. Keep screenshot and OCR execution non-elevated to limit the impact of a compromised dependency.
