How to fix
Restrict network access to the Cocoon instance to trusted users only, or disable the cache feature if the application logic permits.
Technical details
The vulnerability is an information disclosure flaw in Cocoon's caching mechanism: cached values lack proper user isolation, allowing authenticated users to retrieve cached content belonging to other users through normal request handling. This affects all versions of the retired project; exploitation requires network access to the application and does not require special privileges beyond normal user access.
Affected products
