Technical details
The SearchEndpoint in apps/api/plane/app/views/search/base.py checks only for authentication (IsAuthenticated) but fails to verify workspace membership before returning sensitive data. An authenticated attacker can query GET /api/workspaces/{slug}/entity-search/?query_type=user_mention with any known or guessed workspace slug to obtain workspace member and project member information. The fix adds WorkspaceUserPermission checks to enforce that the caller is an active member of the target workspace.
