## Technical details

This vulnerability stems from missing authorization checks on index query endpoints in API Connect. A low-privileged authenticated attacker can directly request arbitrary indices over the network, bypassing intended access controls. The missing authorization allows unauthorized data exposure without requiring additional user interaction or elevated privileges.
