Name of the Vulnerable Software and Affected Versions MISP (affected versions not specified)
Description An authorization bypass exists in the UiBeta theme collection view at the presentation layer. The view template app/View/Themed/UiBeta/Collections/view.ctp performs a secondary query of member events by UUID but fails to apply the caller's access control list (ACL), omitting the createEventConditions() authorization filter. While the CollectionsController::view() action correctly enforces per-user event ACL via Event::fetchSimpleEvents($user, ...), the template's independent query allows an authenticated user with view access to a collection to retrieve full details of events they are not permitted to read. This leads to horizontal privilege escalation, exposing event identifiers, info, dates, timestamps, creator organization, event tags, and galaxy clusters.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
