Robert Munteanu resolved SLING-11658.
-------------------------------------
Resolution: Invalid
Thank you for your report. In the future, please report security issues at
secur...@sling.apache.org, following the process at
https://sling.apache.org/project-information/security.html .
We do not consider this to be a security issue, as accessing the web console
already grants administrative privileges to all of Sling.
