rbyers@ could you help fix this or triage this to a more appropriate owner? Thanks!

The OWNERS file says this is component Tools>Layout (which doesn't exist), so marking this as just "Test" for now.

This looks like this might be test-only code, which might make this Security_Impact-None.

rbyers: Uh oh! This issue still open and hasn't been updated in the last 14 days. This is a serious vulnerability, and we want to ensure that there's progress. Could you please leave an update with the current status and any potential blockers?

If you're not the right owner for this issue, could you please remove yourself as soon as possible or help us find the right one?

If the issue is fixed or you can't reproduce it, please close the bug. If you've started working on a fix, please set the status to Started.

Thanks for your time! To disable nags, add the Disable-Nags label.
