MEDIUM 4.3EPSS 1.87%
Does this matter?
Lower severity and a low EPSS score (1.87%). Track it; it rarely justifies an emergency change on its own.
Description
Nextcloud Server before 9.0.52 & ownCloud Server before 9.0.4 are not properly verifying restore privileges when restoring a file. The restore capability of Nextcloud/ownCloud was not verifying whether a user has only read-only access to a share. Thus a user with read-only access was able to restore old versions.
