CVE-2026-44252
HighCVSS 7.7Summary
Wazuh Manager from version 4.0.0 until 4.14.5 allows a low-privilege read-only API user with manager:read permission to retrieve the cluster key from the element in ossec.conf through GET /manager/configuration?raw=true. An attacker with network access to TCP port 1516 can use the disclosed Fernet key to impersonate a cluster worker and submit distributed API requests containing attacker-controlled rbac_permissions with rbac_mode set to black. Because the master trusts the worker-supplied authorization context, the attacker can create users, assign administrator roles, access credentials and API tokens, modify configuration, and execute actions across agents. This issue is fixed in version 4.14.5.
Risk Assessment
The risk includes full compromise of the Wazuh manager, including creation of administrator accounts, credential theft, and configuration modification, potentially leading to security breaches across the entire infrastructure.
Recommendation
It is recommended to upgrade Wazuh to version 4.14.5 or later to prevent disclosure of the cluster key and resulting privilege escalation.
