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

Remediation
The vendor's own words where we have them.
Upgrade Elastic Agent and Elastic Defend to a fixed release. Apply vendor patches per advisory and restrict external exposure of the affected component until patched.
First 24 hours
Ordered from the record's own fields — exposure first, because you cannot patch what you have not found.
- Identify exposed assets running affected vendor/product/version combinations.
- Prioritize based on EPSS, PoC availability, and external exposure.
- Search available logs for exploit probes, errors, authentication anomalies, or suspicious child processes matching the vulnerability class.

Answered from this record1
What should defenders know first?
CVE-2026-102413 is Uncaught Exception in Elastic Endpoint Leading to Denial of Service, a medium vulnerability affecting Elastic Agent and Elastic Defend from Elastic. The current evidence does not list it in CISA KEV, and the exploit status is: Active exploitation is not confirmed from current sources for CVE-2026-102413. Public exploit evidence is: A public PoC is not confirmed from current sources for CVE-2026-102413. The affected-version evidence is listed in the key facts and affected products tables. Defenders should first verify whether exposed or business-critical assets run those versions, then apply vendor patches or mitigations, restrict reachable attack surface, and preserve logs for detection review. CVSS 6.2 describes technical severity, while EPSS 0% helps estimate near-term exploit likelihood; neither replaces asset context. Unknown fields should remain explicit in tickets, and threat actor, IOC, victimology, or payload claims should not be added unless a cited source supports them. Monitor CISA KEV, vendor advisories, NVD changes, public PoC repositories, and internal telemetry for update triggers.
