CVE-2026-102413: CWE-248 Uncaught Exception in Elastic Elastic Agent and Elastic Defend
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.

Technical Analysis
This vulnerability (CWE-248) occurs when Elastic Defend's Elastic Endpoint component processes a specially crafted file name under specific system locale configurations (including Chinese, Japanese, and Korean) on Windows. The unhandled exception during file-path handling causes the Elastic Endpoint process to crash and restart repeatedly. This results in denial of service by impairing Elastic Defend's malware prevention and behavioral detection capabilities on the affected host.
Potential Impact
The impact is a denial of service condition on the affected host, where Elastic Defend's real-time malware prevention and behavioral detection are degraded or disabled due to repeated crashes of the Elastic Endpoint process. There is no confidentiality or integrity impact reported.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or patch links are provided in the available data. Until a patch is available, consider monitoring for unusual Elastic Endpoint process crashes and avoid processing files with suspiciously crafted names under affected locale settings.
