Nextcloud is an open source content collaboration platform. Prior to version 2.7.2, a privilege escalation vulnerability exists in the Approval app that allows a user without sharing permissions to force the system to share a file with approvers. This results in an authorization bypass and privilege escalation, allowing unauthorized distribution of restricted files. This issue has been patched in version 2.7.2.
