prior to 6.13.23, 6.14.x prior to 7.4.11, 7.5.x prior to 7.11.6 or 7.12.x prior to 7.12.5. It is, therefore, affected by an OGNL injection
vulnerability that would allow an authenticated user, and in some instances an unauthenticated user, to execute
arbitrary code on a Confluence Server or Data Center instance.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version 
number.");
