Detailsinfo

A vulnerability was found in MISP up to 2.5.46 and classified as critical. This issue affects the function queryEnrichment of the file EventsController.php of the component Module Availability Controls. The manipulation of the argument module with an unknown input leads to a input validation vulnerability. Using CWE to declare the problem leads to CWE-20. The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

In MISP, the queryEnrichment method in EventsController.php accepted a module name parameter and iterated over the list of enabled modules to find a match. If the specified module was not present in the enabled modules list, the code silently continued processing using default parameters (format set to 'simplified' and no module-specific configuration applied) rather than rejecting the request. This allowed an authenticated user to trigger enrichment or analysis processing through a module that was not explicitly enabled or available on the instance, bypassing the intended module availability controls. The lack of validation meant that module names outside the enabled set were not rejected, potentially exposing functionality or data processing paths that the administrator had not authorized for use.

The advisory is shared at github.com. The identification of this vulnerability is CVE-2026-95674 since 09/22/2026. The exploitation is known to be easy. The attack may be initiated remotely. Technical details are known, but no exploit is available.
