Summary
A vulnerability in MISP dashboard widgets allowed an authenticated user to manipulate the 'fields' option and influence which fields were returned by the 'New Users' and 'New Organisations' widgets. Requesting an empty field set could cause the query to return unintended model fields, including user email addresses even when disclosure was disabled.
Risk Assessment
An authenticated low-privileged user can disclose restricted user or organization metadata, including email addresses, violating privacy.
Recommendation
Update MISP to a version containing the patch that safely builds the allowed field list and removes restricted fields before processing user selection.
Other vulnerabilities in MISP

An improper authorization check in MISP's attribute creation endpoint allowed an authenticated user with permission to add attributes to submit a sharing_group_id without triggering the corresponding sharing group authorization check, as long as the attribute distribution value was not explicitly set to 4 — 'sharing group'.
- CVE-2017-14337High
In MISP versions before 2.4.80, when configured with X.509 certificate authentication alongside a non-MISP external user management API, an unauthenticated user can gain access as an arbitrary user if the API returns an empty value.
- CVE-2026-10868Critical
MISP has a mass assignment vulnerability in the user edit functionality (UsersController::edit()). An authenticated attacker can modify the user ID in the request, leading to updates on another user's account.
- CVE-2026-10611Critical
MISP contains an authentication bypass vulnerability when LDAP mixed authentication is enabled with OTP enforcement. An authenticated user can bypass the OTP step and access the application without providing a TOTP, HOTP, or email OTP code.

Original NVD description (English source)
A vulnerability in the MISP dashboard widgets allowed an authenticated user to manipulate the fields option and influence which fields were returned by the New Users and New Organisations widgets. In some cases, requesting a field set that became empty after validation or redaction could cause the underlying query to fall back to returning unintended model fields. For the New Users widget, this could allow a non-site-admin user to obtain user e-mail addresses even when user e-mail disclosure was disabled by configuration. For the New Organisations widget, crafted field selection could similarly result in unintended organisation fields being included in the dashboard response. The issue was caused by applying field filtering and redaction in a way that could leave the selected field list empty. The patch ensures that the allowed field list is built safely, that restricted fields such as user e-mail addresses are removed before user-supplied field selection is processed, and that an empty field selection falls back only to the permitted default fields. Impact: An authenticated low-privileged user with access to the affected dashboard widgets may be able to disclose restricted user or organisation metadata, including user e-mail addresses depending on configuration.
