    CVE-2026-74043

    Wazuh from 4.1.1 before 4.14.8 contains a path traversal vulnerability in upload_list_file, upload_rule_file, and upload_decoder_file that allows malicious cluster workers to write files at arbitrary paths. Attackers holding the cluster key can send DistributedAPI requests with ../ sequences in filename, bypassing REST controller validation, to write files as the wazuh user.
