CVE-2026-34929

Published: 2026-05-21 14:16:46
Last Modified: 2026-05-21 15:05:28

Description

An origin validation vulnerability in the Apex One/SEP agent could allow a local attacker to escalate privileges on affected installations. This is similar to CVE-2026-34927 but exists in a different inter-process communication mechanism. Please note: an attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability.
