This is a serious security regression. If you are not able to fix this quickly, please revert the change that introduced it.

No idea why sheriffbot says this is a ReleaseBlock-Stable. The offending commit only made it to the current canary as per https://chromiumdash.appspot.com/commit/f2d07ec516fc069e93df4b2983cbd112a8ade3e9

The fix will make it Canary. I don't think there's any backmerge required here.
