Name of the Vulnerable Software and Affected Versions Wazuh wazuh-modulesd versions prior to 5.0.0-beta3
Description A null pointer dereference occurs in the inventory sync FlatBuffer DataValue handling. An enrolled agent can trigger a denial of service by sending a verifier-valid DataValue message that omits the optional id field. This causes the wazuh-modulesd process to crash when it attempts to dereference data->id()->string view() without performing null validation.
Recommendations Update wazuh-modulesd to version 5.0.0-beta3 or later.
