## Technical details

The vulnerability exists in the search operation handler (ajax.render.php) where user permission checks were not properly enforced. An authenticated attacker with low privileges can craft search requests that return unauthorized object information by exploiting insufficient authorization validation. The vulnerability requires network access and valid user credentials (low privilege account) but no user interaction. An attacker can achieve confidentiality, integrity, and availability impact by accessing, modifying, or disrupting data visibility. The fix was implemented in version 3.2.3 and 3.3.0 by adding proper permission validation in the AjaxRenderController search operation.
