MISP Event Graph Object Reference Lookup Exposes References from Unauthorized Objects
Vulnerability 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

MISP 授权问题漏洞
Vulnerability Description
MISP是MISP组织开源的一个威胁情报共享与分析平台。 MISP 2.5.45及之前版本存在授权问题漏洞,该漏洞源于EventGraphTool::get_reference_data()在通过UUID检索对象引用记录前未验证请求者是否有权访问所属对象,可能导致经过身份验证的用户越权获取对象引用信息。
