- Unpinned and Unnecessary Third-Party Dependencies## Vulnerability Details **File Location**: `requirements.txt:1-2`; installation is instructed by `README.md:15-18` **Vulnerability Type**: T08: Insecure Dependencies **Risk Level**: Medium **Vulnerable Code**: `requirements.txt:1-2` ```text Pillow openpyxl ``` `README.md:15-18` ```markdown ## Installation ```bash pip install -r requirements.txt ``` ``` ### Technical Analysis Both dependencies are installed without exact versions, compatible-version constraints, or package hashes. Consequently, the versions installed depend on the package-index state at installation time rather than versions reviewed with this project. `openpyxl` is not imported by any of the executable scripts and is unrelated to the documented image-processing functionality. Installing an unused package unnecessarily expands the dependency graph and supply-chain attack surface. A malicious or compromised dependency release could potentially run code through package build hooks during installation. A vulnerable or behaviorally incompatible future release could also affect the application at runtime. Exploitation depends on compromise of a package release, package index, configured mirror, or dependency-resolution environment; the project does not itself contain evidence that the named packages are currently malicious. ### Attack Path 1. A user follows the documented installation procedure and runs `pip install -r requirements.txt`. 2. `pip` resolves whichever package versions are currently available because no reviewed versions or hashes are specified. 3. An attacker compromises a future release, package-index account, configured mirror, or another part of the dependency-resolution channel. 4. The unreviewed package artifact is downloaded and installed. 5. Malicious build logic may execute with the privileges of the user performing the installation. Malicious runtime logic in Pillow could subsequently execute when the image-processin ...[truncated 583 chars]
- Remediation
- ## Remediation Suggestions 1. Remove `openpyxl` unless a documented and tested feature requires it. 2. Pin Pillow to a reviewed exact version or a narrowly controlled compatible range. 3. Generate a lock file containing cryptographic hashes and install with hash verification, such as `pip install --require-hashes -r requirements.lock`. 4. Obtain packages only from an explicitly configured trusted index over TLS. 5. Run dependency vulnerability scanning in CI and review dependency updates before merging them. 6. Install and run the Skill in a dedicated virtual environment under a non-privileged account. 7. Keep the requirements manifest synchronized with actual imports and documented capabilities.
