Risk Level: MEDIUMCOMMAND_EXECUTIONPROMPT_INJECTION
Full Analysis
- [COMMAND_EXECUTION]: The skill uses the
image.filepathproperty from an externaldraft.jsonfile directly in a shell command (exiftool -all= "<image.filepath>"). A malicious JSON file could provide a path containing shell metacharacters (e.g., backticks, semicolons) to execute unauthorized commands. - [PROMPT_INJECTION]: The skill is vulnerable to indirect prompt injection. It ingests untrusted data from
draft.jsonand uses it to drive agent actions in a browser. * Ingestion points: TheReadtool is used to loaddraft.jsonas described in SKILL.md. * Boundary markers: No delimiters or instructions are used to separate the tweet text from the agent's instructions. * Capability inventory: The skill has access to theBashtool (forexiftool) andchrome-devtoolsfor browser manipulation. * Sanitization: There is no validation or sanitization of thetweettext orimage.filepathbefore they are used in high-capability tools.
