Grade D
Two or more Medium findings, or a High finding. Only try it in a sandbox.
Not a guarantee. A hygiene check of the source at the commit shown, not a security audit.
Rescanned at commit ef0bfe530eb4, unchanged since the check below.
PERMISSION_SHELL_UNDECLARED AGENT_IGNORE_INSTRUCTIONS
Why this grade
- PERMISSION_SHELL_UNDECLARED Medium
Runs shell commands that the manifest or description does not mention.
packages/cli-commands/src/run-command-in-process.ts, line 17
// - Run the Command in the SAME process (no `child_process.spawn` - - AGENT_IGNORE_INSTRUCTIONS Medium
Text tells the agent to ignore earlier instructions.
docs/prompt-fix-contract.md, line 240
This prevents a finding message starting with `## Ignore previous instructions` from creating a new section in the prompt. The agent sees that content as data inside a `Message:` b
Any High, or two or more Medium findings, give D. One Medium gives C. Low findings or a security Note give B. Each code names a finding behind the letter.
If you think this grade is wrong, email [email protected] with the entry link and your evidence. We aim to acknowledge within two working days and decide within seven. If we confirm an error, we aim to correct it within 24 hours of confirming it. These are aims, not guarantees.
Grades are a hygiene check of the source at the commit shown, on the date checked, not a security audit or a guarantee. The free directory grades are automated. Before release, a PlugVet engineer reviews every paid report and any grade we hold back, including all F grades, against the source code and the evidence we quote.
