This is a serious security regression. If you are not able to fix this quickly, please revert the change that introduced it. If this doesn't affect a release branch, or has not been properly classified for severity, please update the Security_Impact or Security_Severity labels, and remove the ReleaseBlock label. To disable this altogether, apply ReleaseBlock-NA. For more details visit https://www.chromium.org/issue-tracking/autotriage - Your friendly Sheriffbot

Switching you to owner for now. That should let you access the report, but let me know if it doesn't work.

This looks like it may be a dupe of crbug.com/791317 . Waiting for clusterfuzz to see if it's already verified as fixed or not.

Clusterfuzz says this is fixed already, but since it doesn't appear to have de-duped them I'd like to wait for confirmation before closing.
