CVE-2026-48162Public exploitNetwork attack vector

Arbitrary file read via unconstrained DAPI path

Published Aug 19, 2026 · Updated Aug 25, 2026

Path traversal in affected Wazuh manager versions allows remote authenticated users to read any manager-readable file from a cluster master. DistributedAPI.send_tmp_file joins the peer-controlled tmp_file value to WAZUH_PATH without canonicalization or confinement before Handler.send_file opens and returns the resolved path. Access requires network reachability and the shared cluster Fernet key; reading the API signing key enables offline administrator-token forgery.
