What is CVE-2026-114611?

OCO-Server, a self-hosted endpoint management application, contains a vulnerability in its Apple MDM enrollment endpoint. Prior to version 1.2.3, the application improperly validates signed enrollment requests, allowing attackers to exploit the lack of certificate chain verification. By using a self-signed certificate, attackers can forge enrollment requests, leading to device-record hijacking. This enables unauthorized control over victim devices, allowing attackers to read management data, modify push tokens, and disrupt device enrollment. Version 1.2.3 resolves this critical validation issue.

Affected Version(s)

OCO-Server < 1.2.3
