In https://developer.mend.io/github/juju4/velociraptor-offline-collections/-/job/7e465286-f70a-4076-9e79-93b0c3173997, there is correct identification of GHSA-752w-5fwx-jx9f for pyjwt in "DEBUG: alert package rules" and "DEBUG: branches info extended"

Can you help me understand why not opening PR ASAP as per config?

Thanks
