EchelonGraph scoreMEDIUM confidence

This medium-severity CVE scores 6.5 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.4%, top 69% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

Wazuh 4.0.0 before 4.14.6 contains a path traversal vulnerability that allows authenticated cluster peers to delete arbitrary directory contents by supplying a traversal-shaped node name in the cluster hello payload without validation. Attackers holding a valid cluster Fernet key can craft a malicious node name and disconnect, triggering the master's peer cleanup routine to remove the contents of arbitrary directories within the Wazuh installation path writable by the wazuh user.
