{"schemaVersion":3,"id":"CVE-2026-61800","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"Wazuh is an open-source security platform providing unified XDR and SIEM protection for endpoints and cloud workloads. In versions 4.4.0 through 4.14.6, a party holding the cluster key can write, overwrite, or delete arbitrary files under /var/ossec on worker nodes, leading to remote code execution as root. During cluster file synchronization, the non-merged branch of update_master_files_in_worker() moves each staged file to a destination derived only from safe_join(), which confines the path to /var/ossec but never verifies that the file lands in the directory declared by its cluster_item_key. Because the destination check present on the primary node and on the worker's merged branch was not applied, a peer can place files at attacker-chosen locations under /var/ossec, including paths that are executed as root, and the delete branch has the same gap. This is an incomplete fix for CVE-2026-30893, which addressed traversal outside /var/ossec but left this path able to redirect files anywhere within it. This issue is fixed in version 4.14.7.","dates":{"published":"2026-08-27T23:26:28.110Z","modified":"2026-08-28T15:56:58.461Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":9.1,"severity":"critical","version":"3.1","versionLabel":"v3.1","source":"CVE.org","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"CVE.org","score":9.1,"severity":"critical","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"NVD","score":9.1,"severity":"critical","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.00976,"percentile":0.61698,"severity":"low","asOf":"2026-10-21T00:00:00.000Z","change":{"pp":0.362,"baselineDate":"2026-09-21T00:00:00.000Z","baselineScore":0.00614},"history":[{"date":"2026-09-14T00:00:00.000Z","score":0.0059,"percentile":null},{"date":"2026-09-15T00:00:00.000Z","score":0.0059,"percentile":null},{"date":"2026-09-16T00:00:00.000Z","score":0.00614,"percentile":null},{"date":"2026-09-17T00:00:00.000Z","score":0.00614,"percentile":null},{"date":"2026-09-18T00:00:00.000Z","score":0.00614,"percentile":null},{"date":"2026-09-19T00:00:00.000Z","score":0.00614,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.00614,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.00614,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.00614,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.00614,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.00976,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00976,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00976,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00976,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00976,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00976,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00976,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00976,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00976,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00976,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00976,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00976,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00976,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00976,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00976,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00976,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.00976,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.00976,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.00976,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.00976,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.00976,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.00976,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00976,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00976,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00976,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.00976,"percentile":null},{"date":"2026-10-20T00:00:00.000Z","score":0.00976,"percentile":null},{"date":"2026-10-21T00:00:00.000Z","score":0.00976,"percentile":0.61698}],"last30":[{"date":"2026-09-21T00:00:00.000Z","score":0.00614,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.00614,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.00614,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.00976,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00976,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00976,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00976,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00976,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00976,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00976,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00976,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00976,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00976,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00976,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00976,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00976,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00976,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00976,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00976,"percentile":null},{"date":"2026-10-10T00:00:00.00
