{"id":"CVE-2026-61811","url":"https://www.cyber-defence.io/tools/cve/CVE-2026-61811","generatedAt":"2026-10-28T02:58:01.156Z","title":"Wazuh is an open-source security platform providing unified XDR and SIEM protection for endpoints and cloud workloads.","description":"Wazuh is an open-source security platform providing unified XDR and SIEM protection for endpoints and cloud workloads. From 3.8.0 until 4.14.7, the _getattributes() function in src/os_xml/os_xml.c recursively processes every XML attribute without a depth limit while allocating two large local buffers in each stack frame. An enrolled agent can submit a Windows EventChannel event containing an element with enough attributes to exhaust the analysisd worker-thread stack, trigger a segmentation fault, and interrupt log ingestion. The element-depth limit in _ReadElem() does not constrain the number of attributes on one element, so it does not prevent this condition. This issue is fixed in version 4.14.7.","published":"2026-09-24T18:17:17.000Z","lastModified":"2026-09-30T16:44:40.000Z","status":"Awaiting Analysis","sourceIdentifier":"security-advisories@github.com","cvss":{"version":"3.1","score":6.5,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"},"cwe":["CWE-674"],"affected":[],"epss":{"score":0.0037,"percentile":0.30719,"date":"2026-10-26","history":[{"date":"2026-09-25","score":0.0037,"percentile":0.28262}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.37%).
