Risk Level: SAFECOMMAND_EXECUTIONPROMPT_INJECTION
Full Analysis
  • [COMMAND_EXECUTION]: The skill explicitly instructs the agent to use Bash commands to check the ZEPHYR_BAKE_LOG_DIR environment variable at runtime. While intended for configuration, this pattern encourages the use of shell execution for tasks that might have safer alternatives.
  • Mitigation: Utilize native platform methods for accessing environment variables rather than executing shell commands.
  • [PROMPT_INJECTION]: The skill is vulnerable to indirect prompt injection because it processes untrusted text (such as speech-to-text transcriptions of voice memos) from various documents without sanitization.
  • Ingestion points: The routing logic in ROUTING.md reads from documents containing mixed content to identify and extract entries.
  • Boundary markers: Absent. The skill identifies entries using the "For Zephyr N" pattern, which does not provide a secure boundary against instructions embedded in the processed data.
  • Capability inventory: The skill has the capability to read, write, create, and delete file content (via its default move mode) within the local file system, specifically targeting an Obsidian Vault.
  • Sanitization: No sanitization or instruction-filtering is performed on the body of the extracted entries before they are written to target logs.
  • Mitigation: Implement strict delimiters for processed data and provide the agent with explicit instructions to ignore any potential commands or directives found within the entry content.
