{"id":"CVE-2026-48024","summary":"Wazuh: merged-file header path traversal in cluster sync allows arbitrary file write under WAZUH_PATH in Wazuh manager","details":"Wazuh is a free and open source platform used for threat prevention, detection, and response. From 4.0.0 until 4.14.6 and 5.0.0-beta3, cluster.unmerge_info() in framework/wazuh/core/cluster/cluster.py constructs paths from peer-controlled merge_type and name values in a merged synchronization archive. process_files_from_worker() in framework/wazuh/core/cluster/master.py does not adequately confine the resulting path to the declared cluster item directory. A cluster peer holding the shared Fernet key can use traversal in files_metadata.json or a merged-file header to write files such as /var/ossec/etc/ossec.conf. Replacing ossec.conf can configure root-executed commands and lead to code execution when Wazuh services reload. This issue is fixed in versions 4.14.6 and 5.0.0-beta3.","aliases":["GHSA-gh4h-fx78-q8xc"],"modified":"2026-09-17T03:46:42.667204613Z","published":"2026-08-19T16:14:20.847Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-22"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/48xxx/CVE-2026-48024.json"},"references":[{"type":"WEB","url":"https://github.com/wazuh/wazuh/releases/tag/v4.14.6"},{"type":"WEB","url":"https://github.com/wazuh/wazuh/releases/tag/v5.0.0-beta3"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/48xxx/CVE-2026-48024.json"},{"type":"ADVISORY","url":"https://github.com/wazuh/wazuh/security/advisories/GHSA-gh4h-fx78-q8xc"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-48024"},{"type":"FIX","url":"https://github.com/wazuh/wazuh/commit/88fc89fdfb1bf37b9d826e9c281a3d22655733de"},{"type":"FIX","url":"https://github.com/wazuh/wazuh/pull/36204"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/wazuh/wazuh","events":[{"introduced":"8c2c62a6e9dcbcf2c792f7924e8cfdb26842820b"},{"fixed":"44c2925b46bd058d2426bd44ed1b3e5d7b7b03b4"},{"introduced":"cddd833300cb5af494ba7dab31192bae649eb184"},{"fixed":"88fc89fdfb1bf37b9d826e9c281a3d22655733de"},{"fixed":"da844a6fdafd7388d11114841482596d1efdf5b3"}],"database_specific":{"source":["CPE_RANGE","CPE_STRING","REFERENCES"],"cpe":["cpe:2.3:a:wazuh:wazuh:*:*:*:*:*:*:*:*","cpe:2.3:a:wazuh:wazuh:5.0.0:beta1:*:*:*:*:*:*","cpe:2.3:a:wazuh:wazuh:5.0.0:beta2:*:*:*:*:*:*"],"extracted_events":[{"introduced":"4.0.0"},{"fixed":"4.14.6"},{"introduced":"5.0.0-beta1"},{"last_affected":"5.0.0-beta1"},{"introduced":"5.0.0-beta2"},{"last_affected":"5.0.0-beta2"}]}}],"versions":["5.0.0-beta1","5.0.0-beta2","v5.0.0-beta2","v5.0.0-beta1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-48024.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H"}]}
