Summary
An authorization bypass in MISP's EventsController::importModule() allowed authenticated users or read-only API keys with event view access to persist data to events they were not allowed to modify. The write path did not verify event modification rights when processing misp_standard format results.
Risk Assessment
The organization faces a risk of data integrity compromise in MISP, where users with limited privileges can unauthorizedly inject or alter event content, potentially leading to false information in the threat intelligence sharing system.
Recommendation
Update MISP immediately to a version containing the fix that enforces modification-rights checks before processing misp_standard imports.
Other vulnerabilities in MISP
See all- CVE-2026-61474Medium
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.
- CVE-2024-29859Critical
In MISP before version 2.4.187, the add_misp_export function in app/Controller/EventsController.php does not properly check for a valid file upload.
- CVE-2024-25674Critical
An issue was discovered in MISP before version 2.4.184 related to insecure organization logo uploads due to a lack of checks for file extension and MIME type.
- CVE-2023-50918Critical
In app/Controller/AuditLogsController.php in MISP before version 2.4.182, ACLs for audit logs are mishandled.
- CVE-2023-48659Critical
An issue was discovered in MISP before version 2.4.176 related to mishandling parameter parsing in app/Controller/AppController.php.
- CVE-2022-29528Critical
An issue was discovered in MISP before version 2.4.158 related to PHAR deserialization.
- CVE-2021-39302Critical
MISP version 2.4.148, in certain configurations, allows SQL injection via the $conditions['org'] value in the app/Model/Log.php file.
Original NVD description (English source)
An authorization bypass in MISP’s EventsController::importModule() allowed authenticated users or read-only API keys with event view access to persist data to events they were not allowed to modify. When an import module returned results in the misp_standard format, the write path did not verify event modification rights before saving the module output. This could allow a view-only user to inject or alter event data, impacting the integrity of MISP event content. The issue was fixed by enforcing the same modification-rights check used by related module result handling paths before processing misp_standard imports.
