The contacts application in ownCloud before 4.5.10 and 5.x before 5.0.5 does not properly check the ownership of contacts, which allows remote authenticated users to download arbitrary contacts via unspecified vectors.
Weaknesses in this category are related to the management of permissions, privileges, and other security features that are used to perform access control.
