CVE-2026-56401 Details
Description
Rejected reason: This CVE ID has been rejected or withdrawn by its CVE Numbering Authority.
A null pointer dereference vulnerability has been identified in Wazuh versions prior to 5.0.0-beta3, specifically within the 'wazuh-modulesd' component's handling of FlatBuffer 'DataValue' messages during inventory synchronization. This vulnerability allows an enrolled agent to send a valid 'DataValue' message that omits the optional 'id' field. The 'wazuh-modulesd' process crashes when it attempts to dereference 'data->id()->string_view()' without checking for null, leading to a denial-of-service condition.
Users can update to Wazuh version 5.0.0-beta3 or later, where this vulnerability has been patched.
