CVE-2026-78604

Incorrect Permission Assignment for Critical Resource in Elastic Agent Leading to Local Privilege Escalation to SYSTEM

Incorrect Permission Assignment for Critical Resource (CWE-732) in Elastic Agent can lead to local privilege escalation via Replace Binaries (CAPEC-642). On Windows systems where Elastic Agent is installed in unprivileged mode, resources used by the agent service are created with access controls broader than required. A local user could take advantage of this to cause the service to execute code of their choosing, ultimately obtaining SYSTEM-level privileges on the host.
