Bitbucket Data Center webhook receiver skips HMAC signature verification for diagnostics:ping
events after it has already looked up the target template, causing the endpoint to return HTTP
200 for a template that has a Bitbucket DC webhook configured and HTTP 403 otherwise. An
unauthenticated remote attacker can use this response discrepancy as an oracle to enumerate
which Job Template and Workflow Job Template IDs have Bitbucket DC webhooks configured, without
knowing the secret webhook_key.
