Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

Webhooks created by a collaborator keep firing after their repo access is revoked → ongoing real-time exfiltration of private repo content (incomplete revocation cleanup in `DeleteCollaboration`)
