- Unpinned Third-Party Dependencies Permit Unreviewed Code Execution## Vulnerability Details **File Location**: `scripts/generate_image.py:3-7` **Vulnerability Type**: Unbounded third-party dependency resolution **Risk Level**: Medium **Vulnerable Code**: ```python # /// script # requires-python = ">=3.10" # dependencies = [ # "google-genai>=1.0.0", # "pillow>=10.0.0", # ] # /// ``` ### Technical Analysis The inline dependency specification defines only minimum versions for `google-genai` and `pillow`. It does not use exact versions, integrity hashes, or a committed lockfile. When the documented `uv run` command resolves the script environment, it may download and execute any future package version satisfying these constraints. Consequently, the code executed at runtime is not limited to the dependency versions that were present when the Skill was audited. A compromised upstream release, package index account, distribution artifact, or dependency of either declared package could introduce arbitrary code into the execution environment. The dependency installation is related to the Skill's image-generation functionality, but resolving unrestricted future releases exceeds the minimum supply-chain trust necessary to perform that function. ### Attack Path 1. An attacker compromises an upstream package release process, package index account, or qualifying transitive dependency. 2. The attacker publishes a malicious version satisfying `google-genai>=1.0.0` or `pillow>=10.0.0`. 3. A user invokes the Skill through the documented `uv run` command in an environment where the malicious version is selected. 4. `uv` downloads and installs the unreviewed package version. 5. Malicious package code executes during import, initialization, or ordinary runtime operations. 6. The code runs with the same operating-system identity and permissions as the Skill process. ### Impact Assessment Successful exploitation could provide arbitrary code execution with the Agent user's privileges ...[truncated 458 chars]
- Remediation
- ## Remediation Suggestions - Pin every direct dependency to an exact, reviewed version rather than using open-ended lower bounds. - Generate and commit a lockfile that includes all transitive dependencies. - Require cryptographic artifact hashes where supported. - Install packages only from a trusted, explicitly configured package index. - Perform dependency updates through a controlled review and testing process. - Run the Skill in an isolated environment with access limited to the required images, output directory, and Gemini credential. - Add automated software-composition analysis and package integrity checks to the release process.
