CVE-2026-24004: Fleet: Unauthenticated Android device disenrollment vulnerability via Pub/Sub endpoint

Noroxi assessment

Priority: Monitor (action score 6/100)

  • 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: 0.29% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: github.com/fleetdm/fleet/v4 (Go) 4.80.1; govulncheck-vulndb (openSUSE:Leap 15.6) 0.0.20260317T205859-150000.1.152.1.

Low priority for now. Upgrade to github.com/fleetdm/fleet/v4 (Go) 4.80.1; govulncheck-vulndb (openSUSE:Leap 15.6) 0.0.20260317T205859-150000.1.152.1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

Fleet is open source device management software. In versions prior to 4.80.1, a vulnerability in Fleet’s Android MDM Pub/Sub handling could allow unauthenticated requests to trigger device unenrollment events. This may result in unauthorized removal of individual Android devices from Fleet management. If Android MDM is enabled, an attacker could send a crafted request to the Android Pub/Sub endpoint to unenroll a targeted Android device from Fleet without authentication. This issue does not grant access to Fleet, allow execution of commands, or provide visibility into device data. Impact is limited to disruption of Android device management for the affected device. Version 4.80.1 fixes the issue. If an immediate upgrade is not possible, affected Fleet users should temporarily disable Android MDM.
