"The version of Wazuh Server on the remote host is at least 4.0.0 and prior to 4.14.6. It is, therefore, affected by
multiple vulnerabilities, including:

  - cluster.unmerge_info() constructs paths from peer-controlled merge_type and name values in a merged
    synchronization archive. A cluster peer holding the shared Fernet key can use traversal to write arbitrary
    files such as ossec.conf, leading to code execution when Wazuh services reload. (CVE-2026-48024)

  - DistributedAPI.send_tmp_file() joins an attacker-controlled tmp_file value to WAZUH_PATH without
    canonicalization. A cluster peer can use traversal to read any file accessible to the master, including
    the API private key, allowing forged administrator tokens. (CVE-2026-48162)

  - AffectedItemsWazuhResult.merge() trusts the sort_casting field in a cluster worker's JSON response. A
    compromised worker can set sort_casting to exec and place Python source in affected_items, causing the
    master to execute the payload as root. (CVE-2026-44901)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
