Risk Level: MEDIUMCOMMAND_EXECUTIONPROMPT_INJECTION
Full Analysis
  • [COMMAND_EXECUTION]: The skill instructions direct the agent to use grep with user-supplied input: Grep to search the knowledge graph for the component: "$ARGUMENTS". This pattern is susceptible to command injection if the user provides shell metacharacters (e.g., ;, |, `) within the arguments, potentially allowing execution of arbitrary commands on the host system.
  • [PROMPT_INJECTION]: The skill is vulnerable to indirect prompt injection (Category 8) because it processes untrusted data to determine its next steps.
  • Ingestion points: The agent reads data from .understand-anything/knowledge-graph.json (SKILL.md).
  • Boundary markers: The instructions lack delimiters or explicit warnings to the agent to ignore any natural language instructions that might be embedded within the JSON summaries or tags.
  • Capability inventory: The agent possesses the capability to execute shell commands (grep) and read arbitrary files from the filesystem (SKILL.md).
  • Sanitization: No sanitization or validation logic is defined for the content extracted from the knowledge graph before it is used to perform file reads or generate explanations.
