CVE-2026-102413— Uncaught Exception in Elastic Endpoint Leading to Denial of Service

Quick assessment

Affected
Elastic Elastic Agent and Elastic Defend
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Elastic Endpoint 中存在未捕获异常（CWE-248），可通过精心构造的文件名导致拒绝服务。当 Elastic Defend 的 Elastic Endpoint 组件在 Windows 系统上处理文件名时，若系统区域设置包含中文、日文或韩文等本地化配置，可能在文件路径处理过程中引发未处理的异常。该异常会导致 Elastic Endpoint 进程反复崩溃并重启，从而在问题持续期间削弱或完全禁用受影响主机上的 Elastic Defend 实时恶意软件防护和行为检测能力。

Vulnerability Title
Uncaught Exception in Elastic Endpoint Leading to Denial of Service
Source: CVE Program / CVE List V5
Vulnerability Description
Uncaught Exception (CWE-248) in Elastic Endpoint can lead to denial of service via a specially crafted file name. 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.
