=3.10" # dependencies = [ # "google-genai>=1.0.0", # "pillow>=10.0.0", # ] # /// ``` ### Technical Analysis The script declares its runtime dependencies using minimum-version constraints without exact versions, upper bounds, package hashes, or a committed lockfile. The documented execution workflow uses `uv run`, which can resolve and install a future package release that satisfies these constraints. Consequently, the code reviewed during this audit is not sufficient to determine the exact third-party code that will execute in future invocations. A compromised package release, malicious maintainer update, or unexpected incompatible release of `google-genai` or `pillow` could be installed without a separate review. This finding does not establish that the currently available packages are malicious. It identifies an unsafe dependency-resolution practice that creates a supply-chain exploitation path. ### Attack Path 1. An attacker compromises the publication process, maintainer account, or distribution channel of a permitted dependency. 2. The attacker publishes a malicious version whose version number satisfies `google-genai>=1.0.0` or `pillow>=10.0.0`. 3. A user invokes the documented `uv run` command in an environment that has not locked the dependency to a previously reviewed version. 4. The dependency resolver downloads and installs the malicious release. 5. Package code executes in the Python process with the operating-system permissions of the user running the skill. ### Impact Assessment Successful exploitation could provide arbitrary code execution under the invoking user's account. Depending on that account's permissions, an attacker could access local files, environment variables ...[truncated 261 chars]- Remediation

", # "pillow==", # ] ``` 2. Generate and commit a lockfile that records all direct and transitive dependency versions. 3. Use package hash verification where supported to ensure downloaded artifacts match approved files. 4. Perform dependency upgrades through a controlled review process rather than resolving unrestricted future releases at runtime. 5. Run dependency vulnerability and provenance checks in CI before accepting lockfile updates. 6. Prefer an isolated environment with only the filesystem and network permissions required for image generation. ]]>
