Description
DSpace is an open source turnkey repository application. In version 7.0, any community or collection administrator can escalate their permission up to become system administrator. This vulnerability only exists in 7.0 and does not impact 6.x or below. This issue is patched in version 7.1. As a workaround, users of 7.0 may temporarily disable the ability for community or collection administrators to manage permissions or workflows settings.
