In versions 4.0.0 through 4.10.3 and 4.11.0 through 4.14.4, a logic flaw affects the Wazuh Manager's enrollment daemon (authd) and synchronization daemon (remoted). The authd process allows agents to select a group during enrollment but does not filter path traversal sequences such as \"...\" While the manager checks for the group directory using wopendir(), the \"..\" sequence references the parent directory (/var/ossec/etc), allowing it to pass validation. After the malicious group is accepted and stored in the manager's global database, the remoted process uses this unchecked value to build paths for agent configuration synchronization. As a result, sensitive files from /var/ossec/etc, such as client.keys, ossec.conf, and internal certificates, are included in the agent's shared configuration stream and exposed to the attacker. This issue has been fixed in versions 4.10.4 and 4.14.5.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","score":7.5},"cwes":["CWE-22"],"references":["https://github.com/wazuh/wazuh/security/advisories/GHSA-6q95-fcwc-4h44","https://github.com/wazuh/wazuh/security/advisories/GHSA-6q95-fcwc-4h44"],"products":["wazuh:wazuh"],"source":"nvd","synced_at":"2026-10-19T22:45:36.895656543+00:00"},"epss":{"cve":"CVE-2026-39359","score":0.0036,"percentile":0.29821,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
