When Elastic Defend's Elastic Endpoint component processes a file name under certain system locale configurations (including Chinese, Japanese, and Korean locales) on Windows, an unhandled exception can occur during file-path handling. This causes the Elastic Endpoint process to crash and restart repeatedly, which can degrade or disable Elastic Defend's real-time malware prevention and behavioral detection capabilities on the affected host for as long as the condition persists.","publishedAt":"2026-10-06T19:31:46.232Z","updatedAt":"2026-10-06T19:54:08.886Z","severity":{"score":6.2,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","source":"elastic"},"assigner":"elastic","products":["Elastic Elastic Agent and Elastic Defend"],"affected":[{"vendor":"Elastic","product":"Elastic Agent and Elastic Defend","defaultStatus":"unaffected","versions":[{"version":"8.19.13","status":"affected","lessThanOrEqual":"8.19.21","versionType":"semver"},{"version":"9.2.7","status":"affected","lessThanOrEqual":"9.2.8","versionType":"semver"},{"version":"9.3.0","status":"affected","lessThanOrEqual":"9.3.8","versionType":"semver"},{"version":"9.4.0","status":"affected","lessThanOrEqual":"9.4.7","versionType":"semver"},{"version":"9.5.0","status":"affected","lessThanOrEqual":"9.5.4","versionType":"semver"}]}],"references":["https://discuss.elastic.co/t/elastic-agent-endpoint-8-19-22-9-4-8-and-9-5-5-security-update-esa-2026-194/390868"],"weaknesses":["CWE-248"],"ingestedAt":"2026-10-29T20:10:13.529Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/102xxx/CVE-2026-102413.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-102413","state":"PUBLISHED","datePublished":"2026-10-06T19:31:46.232Z","dateUpdated":"2026-10-06T19:54:08.886Z","assignerShortName":"elastic","assignerOrgId":"271b6943-45a9-4f3a-ab4e-976f3fa05b5a","dateReserved":"2026-09-29T02:06:02.426Z"},"containers":{"cna":{"title":"Uncaught Exception in Elastic Endpoint Leading to Denial of Service","descriptions":[{"lang":"en","value":"Uncaught Exception (CWE-248) in Elastic Endpoint can lead to denial of service via a specially crafted file name.
