CVE-2026-102413: Elastic Agent And Elastic Defend

Medium severity, CVSS 6.2. EPSS: 0.1% chance of exploitation in the next 30 days.

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.

Affected products

• Elastic Elastic Agent And Elastic Defend: from 8.19.13, up to and including 8.19.21; from 9.2.7, up to and including 9.2.8; from 9.3.0, up to and including 9.3.8; from 9.4.0, up to and including 9.4.7; from 9.5.0, up to and including 9.5.4
