CVE-2026-26060: Fleetdm Fleet

High severity, CVSS 8.8. EPSS: 0.5% chance of exploitation in the next 30 days.

Fleet is open source device management software. Prior to 4.81.0, a vulnerability in Fleet’s password management logic could allow previously issued password reset tokens to remain valid after a user changes their password. As a result, a stale password reset token could be reused to reset the account password even after a defensive password change. Version 4.81.0 patches the issue.

Affected products

• Fleetdm Fleet: before 4.81.0 (fixed in 4.81.0)
