Limited Authentication Bypass for Media Files
Prior to Opencast 10.14 and 11.7, users could pass along URLs for files belonging to organizations other than the user's own, which Opencast would then import into the current organization, bypassing organizational barriers.
Impact
The vulnerability allows attackers to bypass organizational barriers. Attackers must have full access to Opencast's ingest REST interface, and also know internal links to resources in another organization of the same Opencast cluster.
If you do not run a multi-tenant cluster, you are not affected by this issue.
Patches
This issue is fixed in Opencast 10.14 and 11.7.
