Table Image

Security checks for vulnerabilities and agentic risk

Overview

This skill is a small table-to-image helper with a normal third-party tool dependency, but users should pin or verify that dependency before installing it.

Before installing, prefer a pinned reviewed tablesnap release or commit instead of @latest or the moving default branch. Run it as a normal unprivileged user and only pass table content you intend to render.

Vulnerability Patterns

Insecure DependenciesIntroduces malicious components through unsafe dependency sources
Skill Instruction HijackingAlters the agent's session goals or safety constraints when the skill loads
Agent Memory PoisoningWrites attacker-controlled rules into memory that affect later sessions
Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally

go build -trimpath -o tablesnap ./cmd/tablesnap ``` 3. Publish the expected commit identifier and SHA-256 checksum for the resulting binary or approved release artifact. 4. Prefer signed releases and document how users must verify the signature against a trusted maintainer key before execution. 5. Review and lock transitive Go dependencies in the approved source revision. Preserve the corresponding `go.mod` and `go.sum` files. 6. Document a controlled update process in which new versions are reviewed, tested, and assigned updated integrity values before the installation instructions are changed. 7. Recommend installation and execution under an unprivileged account with only the filesystem and network access necessary to generate the requested image. ]]>
