# CVE-2024-14047: Improper Link Resolution Before File Access ('Link Following') in Winlogbeat Leading to Arbitrary File Write and Denial of Service

- Severity: CVSS 7.2 (High), CNA
- Vector: CVSS:3.1/AV:L/AC:H/PR:L/UI:R/S:C/C:N/I:H/A:H
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=partial
- Known exploited (CISA KEV): no
- Published: 2026-09-01 · Updated: 2026-09-01

## Affected

- Elastic Elastic Security: from 7.6.0, through 8.12.2

## Description

A local vulnerability in the Winlogbeat Windows installer caused runtime files to be placed in a directory writable by unprivileged users. A low-privileged attacker with existing access to the system could pre-position malicious filesystem links, causing a subsequent elevated Winlogbeat operation to write to or delete arbitrary files. Successful exploitation could result in a denial of service.
