three critical (9.1) advisories for wazuh i reported were published today. same trust assumption broken in three places: the cluster fernet key authenticates membership, and the cluster protocol then lets that peer pick filesystem paths.

CVE-2026-49441: the peer-supplied metadata key in process_files_from_worker is used directly as the destination path. write etc/ossec.conf, root rce via wazuh-logcollector.

CVE-2026-48024: same function, merged-file branch. traversal in the merged header name and in merge_type.

CVE-2026-48162: the DAPI tmp_file field is joined to WAZUH_PATH with os.path.join and shipped back to the peer. absolute paths win, so it reads anything the wazuh user can open. grab private_key.pem, forge ES512 admin jwts offline. survives cluster key rotation, since the jwt keypair is a different scope.

patched in 4.14.6.
