CVE-2026-34386Network attack vector

Database disclosure and corruption via bootstrap SQL injection

Published Mar 27, 2026 · Updated Mar 27, 2026

SQL injection in Fleet before 4.81.0 allows remote authenticated users to read or alter database data through MDM bootstrap configuration. The bootstrap-package configuration path accepts crafted administrator-controlled values without sufficient server-side validation, allowing them to alter intended database queries. Exploitation requires Team Admin or Global Admin privileges and Apple MDM enabled; successful requests can corrupt cross-team configuration, disclose password hashes and API tokens, and escalate privileges.
