      "title": "MISP Dashboard Organisation Widgets Bypass Organisation-Index Restrictions and Expose Hidden Organisation Data",
      "summary": "Affected versions of MISP contain inconsistent authorization checks across dashboard widgets that display organisation information.\n\n\nSeveral 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.\n\n\nThe affected widgets included paths that:\n\n\n\n  *  \nreturned organisation names and identifiers;\n\n\n  *  \ncould expose additional organisation database fields through JSON export because unrestricted find('all') queries fetched full rows;\n\n\n  *  \naccepted limit=0 or negative values in a way that could effectively remove the result limit and return the entire organisation table.\n\n\n\n\n\nA 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.\n\nVersion affected: ≤2.5.45",
