{"apiVersion":"1.0","identifier":"CVE-2026-48162","description":"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.","publishedAt":"2026-08-19T17:18:51","lastModifiedAt":"2026-08-25T03:16:55","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-48162","cvssScore":9.1,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H","epssProbability":0.0051,"riskScore":0.95,"affectedProduct":"Wazuh","affectedVersions":">=4.0.0,<4.14.6,==5.0.0-beta3","vulnerabilityType":"Critical software","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-48162","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-48162","en":"https://www.redsauce.net/en/cves/CVE-2026-48162","fr":"https://www.redsauce.net/fr/cves/CVE-2026-48162","pt":"https://www.redsauce.net/pt/cves/CVE-2026-48162","de":"https://www.redsauce.net/de/cves/CVE-2026-48162","sk":"https://www.redsauce.net/sk/cves/CVE-2026-48162","el":"https://www.redsauce.net/el/cves/CVE-2026-48162"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-48162"}}
