Detailsinfo

A vulnerability was found in MISP up to 2.5.45. It has been classified as problematic. This affects an unknown functionality of the component Dashboard Widget. The manipulation of the argument limit with an unknown input leads to a privileges management vulnerability. CWE is classifying the issue as CWE-269. The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor. This is going to have an impact on confidentiality. The summary by CVE is:

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. 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

The advisory is shared at github.com. This vulnerability is uniquely identified as CVE-2026-86441 since 09/07/2026. The exploitability is told to be easy. It is possible to initiate the attack remotely. Technical details are known, but no exploit is available. The price for an exploit might be around USD $0-$5k at the moment (estimation calculated on 09/07/2026). MITRE ATT&CK project uses the attack technique T1068 for this issue.
