CVE-2026-34385Network attack vector

Database compromise via stored UDID interpolation

Published Mar 27, 2026 · Updated Mar 27, 2026

Second-order SQL injection in Fleet before 4.81.0 allows remote authenticated users to read and write its database through Apple MDM. The Apple MDM Authenticate handler stores a malicious device UDID through a parameterized query, but an asynchronous profile-delivery worker later interpolates it directly into four SQL subqueries while multiple statements are enabled. Apple MDM must be enabled, and the attacker must control an enrolled device with a valid SCEP-issued certificate; successful injection exposes secrets and permits arbitrary database changes, including administrator-account creation.
