Several organisation-related widgets did not honor Security.hide_organisation_index_from_users. As a result, authenticated users without the perm_sharing_group permission could enumerate organisations even though the normal organisation index was intentionally hidden from them.
The affected widgets included paths that:
*
returned organisation names and identifiers;
*
could expose additional organisation database fields through JSON export because unrestricted find('all') queries fetched full rows;
*
accepted limit=0 or negative values in a way that could effectively remove the result limit and return the entire organisation table.
A related organisation-contributor leaderboard also ignored the same visibility setting. Its handler counted Event.orgc_id across the entire event table and mapped those IDs to organisation names, revealing every organisation with events regardless of whether the caller could see any of those events. The fix withdraws this widget entirely for users who lack organisation-index visibility.
Version affected: ≤2.5.45

| Description | Affected versions of MISP contain inconsistent authorization checks across dashboard widgets that display organisation information. Several organisation-related widgets did not honor Security.hide_organisation_index_from_users.
