Title

CoopCycle coopcycle-web before 6.20.1 IDOR via Incident Resource and Action Endpoint

Summary

CoopCycle coopcycle-web before 6.20.1 contains a broken access control vulnerability that allows any courier to read and modify every incident because Incident operations only check ROLE_COURIER. Attackers can enumerate sequential incident ids and use PUT /api/incidents/{id}/action to re-price, cancel or reschedule other stores' orders and tasks.
