AI Security Review
scanned 3d ago · by lpm-firewall-aiThe CLI contains a conditional reviewer-manipulation instruction that explicitly suppresses findings and summaries for selected workflow changes. This is a concrete review-integrity attack, even though the credential routing inspected is based on the configured provider endpoint.
Static reason
One or more suspicious static signals were detected.
Trigger
A user runs the review command on a PR whose workflow diff calls MakerXStudio/yoke/.github/workflows/review.yml.
Impact
AI reviewers may omit security findings about the workflow, misleading the user and weakening review of changes to the package’s own CI.
Mechanism
The CLI appends a conditional note to the generated review request telling AI reviewers not to report or summarize specified workflow choices.
Attack narrative
When a PR changes a workflow that calls Yoke’s reusable review workflow, the CLI injects a note into the AI review request that directs reviewers to suppress findings about specified workflow choices and omit them from summaries. This can conceal defects in the workflow from users relying on the package’s review command.
AI rationale
The CLI contains a conditional reviewer-manipulation instruction that explicitly suppresses findings and summaries for selected workflow changes. This is a concrete review-integrity attack, even though the credential routing inspected is based on the configured provider endpoint.
Evidence

Decision evidence
public snapshotAI called this Malicious at 98.0% confidence as Malware with low false-positive risk.
Evidence for block
- The review command runs AI reviewers on a PR and combines their findings.
- When a PR diff changes a workflow calling Yoke’s reusable review workflow, the CLI adds a special note to the review request.
- That note tells reviewers not to raise specified workflow choices as findings or mention them in summaries.
- The generated note is included in the request sent to the reviewers.
Evidence against
- Provider credentials are routed to endpoints derived from the configured provider base URL.
- The package exposes its behavior through a CLI command rather than an install hook.
