Summary
Wazuh Manager - NDJSON Injection in inventory_sync via Agent-Controlled DataValue.index
Details

Wazuh Manager before 5.0.0-beta3 fails to escape the DataValue.index field when constructing OpenSearch bulk requests, allowing enrolled agents to inject arbitrary NDJSON operations. Attackers can smuggle delete, index, or update operations into bulk requests executed under the manager's admin credentials, enabling document deletion, alert tampering, and cross-agent SIEM state manipulation.
