CVE-2026-34385: Fleet's Apple MDM profile delivery has second-order SQL injection that can compromise the database

Noroxi assessment

Priority: Monitor (action score 24/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.20% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: github.com/fleetdm/fleet/v4 (Go) 4.81.0.

Low priority for now. Upgrade to github.com/fleetdm/fleet/v4 (Go) 4.81.0 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

Fleet is open source device management software. Prior to 4.81.0, a second-order SQL injection vulnerability in Fleet's Apple MDM profile delivery pipeline could allow an attacker with a valid MDM enrollment certificate to exfiltrate or modify the contents of the Fleet database, including user credentials, API tokens, and device enrollment secrets. Version 4.81.0 patches the issue.
