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.

Another bug with a stacktrace that has nothing to do with my CL. I'm looking into this to try figure out why CF thinks my CL is the culprit.
