{"id":"CVE-2026-48162","summary":"Wazuh: cluster peer can read arbitrary master files and forge offline REST API administrator tokens via DAPI tmp_file path injection 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, DistributedAPI.send_tmp_file() in framework/wazuh/core/cluster/dapi/dapi.py joins an attacker-controlled tmp_file value to WAZUH_PATH without canonicalization or confinement. A cluster peer holding the shared Fernet key can use traversal or an absolute path to make the master return any readable file over the cluster channel. Reading /var/ossec/api/configuration/security/private_key.pem allows the peer to forge administrator REST API tokens offline and then exercise administrative privileges without creating an account. This issue is fixed in versions 4.14.6 and 5.0.0-beta3.","aliases":["GHSA-r6f5-h662-8ffc"],"modified":"2026-08-21T03:46:47.510303304Z","published":"2026-08-19T16:13:15.857Z","database_specific":{"cwe_ids":["CWE-73"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/48xxx/CVE-2026-48162.json","cna_assigner":"GitHub_M"},"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-2026-48162.json"},{"type":"ADVISORY","url":"https://github.com/wazuh/wazuh/security/advisories/GHSA-r6f5-h662-8ffc"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-48162"},{"type":"FIX","url":"https://github.com/wazuh/wazuh/commit/de1eeedbe336744934be4e20d87d84a76e438cee"},{"type":"FIX","url":"https://github.com/wazuh/wazuh/pull/36246"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/wazuh/wazuh","events":[{"introduced":"8c2c62a6e9dcbcf2c792f7924e8cfdb26842820b"},{"introduced":"cddd833300cb5af494ba7dab31192bae649eb184"},{"fixed":"44c2925b46bd058d2426bd44ed1b3e5d7b7b03b4"},{"fixed":"da844a6fdafd7388d11114841482596d1efdf5b3"},{"fixed":"de1eeedbe336744934be4e20d87d84a76e438cee"}],"database_specific":{"extracted_events":[{"introduced":"4.0.0"},{"fixed":"4.14.6"},{"introduced":"5.0.0-beta1"},{"fixed":"5.0.0-beta3"}],"source":["AFFECTED_FIELD","REFERENCES"]}}],"versions":["v5.0.0-beta2","v5.0.0-beta1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-48162.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"}]}
