Detailed vulnerability description

The vulnerability allows a remote user to gain access to sensitive information.

The vulnerability exists due to improper access restrictions at the "/services/streams/search" endpoint. A remote low-privileged user can run a saved search with a risky command using the permissions of a higher-privileged user to bypass the SPL safeguards for risky commands by circumventing endpoint restrictions using character encoding in the REST path passed via the "q" parameter to the affected endpoint.
