{"id":"CVE-2026-48162","aliases":[],"url":"https://o3.security/vulnerability/CVE-2026-48162","summary":"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…","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.","published":"2026-08-19T17:18:51.233","modified":"2026-08-19T17:18:51.233","cvss":{"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"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":{"url":"https://github.com/wazuh/wazuh/commit/de1eeedbe336744934be4e20d87d84a76e438cee","label":"wazuh/wazuh@de1eeed"},"references":[{"type":"WEB","url":"https://github.com/wazuh/wazuh/commit/de1eeedbe336744934be4e20d87d84a76e438cee"},{"type":"WEB","url":"https://github.com/wazuh/wazuh/pull/36246"},{"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":"WEB","url":"https://github.com/wazuh/wazuh/security/advisories/GHSA-r6f5-h662-8ffc"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-08-19T17:18:51.233"}}
