- Summary
- MISP Event Report Cross-Event Reparenting via Unscoped UUID Resolution in editReport
- Details
-
When a user creates or edits a report inside an event, MISP can identify an existing report using its UUID without properly checking whether that report actually belongs to the same event.
As a result, a user who has editing rights on one event could potentially move a report from another event into their own event, as long as they know or can guess the report’s UUID. Once moved, they could view and change information that they were not originally allowed to access.
The vulnerability requires the attacker to have editor access to at least one event and to know or discover a valid report UUID.
The main impact is that private event reports could be exposed or modified across event boundaries, bypassing MISP’s normal access restrictions.
