3 findings — 3 medium severity. This skill can be installed but you should review these findings before use.
W011: Third-party content exposure detected (indirect prompt injection risk)
What this means
The skill exposes the agent to untrusted, user-generated content from public third-party sources, creating a risk of indirect prompt injection. This includes browsing arbitrary URLs, reading social media posts or forum comments, and analyzing content from unknown websites.
Why it was flagged
Third-party content exposure detected (high risk: 0.80). The skill explicitly ingests and analyzes untrusted third‑party container content (e.g., images and files from registries and exported container filesystems) and related artifacts — see SKILL.md steps (docker export/inspect, docker logs, dive/container-diff, trivy scans) and scripts/agent.py functions (inspect_container, export_container, get_container_logs, scan_image_vulnerabilities) — and uses that content to drive analysis and reporting, so arbitrary content could influence decisions.
W012: Unverifiable external dependency detected (runtime URL that controls agent)
What this means
The skill fetches instructions or code from an external URL at runtime, and the fetched content directly controls the agent’s prompts or executes code. This dynamic dependency allows the external source to modify the agent’s behavior without any changes to the skill itself.
Why it was flagged
Potentially malicious external URL detected (high risk: 0.80). The skill explicitly downloads and installs/executes remote binaries at runtime—e.g., wget https://github.com/wagoodman/dive/releases/latest/download/dive_linux_amd64.deb and curl -LO https://storage.googleapis.com/container-diff/latest/container-diff-linux-amd64—which fetch and run remote code and are used as required tools for the image-layer analysis steps.
W013: Attempt to modify system services in skill instructions
What this means
The skill prompts the agent to compromise the security or integrity of the user’s machine by modifying system-level services or configurations, such as obtaining elevated privileges, altering startup scripts, or changing system-wide settings.
Why it was flagged
Attempt to modify system services in skill instructions detected (high risk: 0.80). The skill explicitly instructs installing packages with sudo (sudo dpkg -i) and performs host-level Docker operations (commit/save/export, reading/writing /var/lib/docker and other host paths), which require elevated privileges and modify the machine's state, so it should be flagged.
