Attackers exploit insufficient validation in OS_IsValidName() and unsafe path concatenation in delete_diff() to resolve the traversal to the parent queue directory, causing its subdirectories to be removed and stopping all Wazuh services requiring manual recovery.","published":"2026-08-18T18:19:33.610","modified":"2026-08-18T18:19:33.610","cvss":{"score":7.1,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":{"url":"https://github.com/wazuh/wazuh/pull/35833","label":"wazuh/wazuh#35833"},"references":[{"type":"WEB","url":"https://github.com/wazuh/wazuh/pull/35833"},{"type":"WEB","url":"https://github.com/wazuh/wazuh/security/advisories/GHSA-573w-mqw4-jvmr"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/wazuh-path-traversal-dos-via-agent-enrollment"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-08-18T18:19:33.610"}}
