CyberRota Analysis
AI-GeneratedAuthenticated users of MISP versions up to 2.5.45 can exploit a lack of access control to retrieve object-reference records by UUID, potentially exposing sensitive information outside their authorized scope. This vulnerability arises from the absence of parent-object ACL checks, allowing unauthorized data access when a user knows a reference UUID. Organizations using affected versions should prioritize patching to mitigate the risk of unauthorized data exposure.

Original NVD Description
Affected versions of MISP allow authenticated users to retrieve object-reference records by UUID through EventGraphTool::get_reference_data() without first checking whether the requester is authorized to view the object the reference belongs to. The vulnerable code queried ObjectReference.uuid directly and returned the matching row whenever it existed. Because no parent-object ACL was applied, a user who knew or obtained a reference UUID could retrieve information associated with an object outside their normal access scope. The commit explicitly states that any object reference could be returned by UUID without authorizing its parent object. The fix retrieves the referenced object's object_id and calls fetchObjectSimple() with the current user. If the user cannot access that parent object, MISP now returns NotFoundException instead of exposing the reference. Version affected: ≤2.5.45
