CVE-2018-8949
Estado: ModificadaMedia (4.3)—
An issue was discovered in app/Model/Attribute.php in MISP before 2.4.89. There is a critical API integrity bug, potentially allowing users to delete attributes of other events. A crafted edit for an event (without attribute UUIDs but attribute IDs set) could overwrite an existing attribute.
