Nextcloud Server before 9.0.55 and 10.0.2 suffers from a bypass in the quota limitation. Due to not properly sanitizing values provided by the OC-Total-Length HTTP header an authenticated adversary may be able to exceed their configured user quota. Thus using more space than allowed by the administrator.
