{"cve":"CVE-2026-44252","nvd":{"published":"2026-08-19T16:17:10.690","modified":"2026-10-27T11:10:00.193","status":"Analyzed","description":"Wazuh is a free and open source platform used for threat prevention, detection, and response. From 4.0.0 until 4.14.5, Wazuh Manager allows a low-privilege read-only API user with manager:read permission to retrieve the cluster key from the element in ossec.conf through GET /manager/configuration?raw=true. An attacker with network access to TCP port 1516 can use the disclosed Fernet key to impersonate a cluster worker and submit distributed API requests containing attacker-controlled rbac_permissions with rbac_mode set to black. Because the master trusts the worker-supplied authorization context, the attacker can create users, assign administrator roles, access credentials and API tokens, modify configuration, and execute actions across agents. This issue is fixed in version 4.14.5.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","score":7.7},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":8.8},"cwes":["CWE-863"],"references":["https://github.com/wazuh/wazuh/commit/b3459f5663702aea14e91330a7a6912081fed2eb","https://github.com/wazuh/wazuh/pull/35307","https://github.com/wazuh/wazuh/releases/tag/v4.14.5","https://github.com/wazuh/wazuh/releases/tag/v5.0.0-beta3","https://github.com/wazuh/wazuh/security/advisories/GHSA-34fx-c2xw-xcpg"],"products":["wazuh:wazuh"],"source":"nvd","synced_at":"2026-10-27T11:28:04.741528231+00:00"},"epss":{"cve":"CVE-2026-44252","score":0.00544,"percentile":0.45414,"date":"2026-10-26"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
