CVE-2026-39359Public exploitNetwork attack vector

Sensitive-file disclosure via unchecked enrollment group path

Published Jul 16, 2026 · Updated Jul 16, 2026

Path traversal in Wazuh Manager 4.0.0 through 4.10.3 and 4.11.0 through 4.14.4 allows remote attackers to read sensitive files. The authd daemon concatenates an agent-supplied group name into the shared-configuration directory and accepts .. because wopendir() resolves it to /var/ossec/etc; remoted then copies that directory into the agent synchronization cache. Enrollment port 1515 must be reachable, and successful exploitation exposes manager configuration, agent keys, and internal certificates without altering or interrupting the service.
