CVE-2026-26060 Â (opens in a new tab)How to fix?
Upgrade github.com/fleetdm/fleet/server/service to version 4.81.0 or higher.
Overview
Affected versions of this package are vulnerable to Insufficient Session Expiration in the password reset process. An attacker can gain unauthorized access to a user's account by reusing a previously obtained password reset token within its validity period, even after the user has changed their password. This is only exploitable if the attacker has already compromised a valid password reset token and uses it within the 24-hour expiration window.
Workaround
This vulnerability can be mitigated by waiting for the reset token to expire before reusing the account or by contacting an administrator to invalidate active sessions.
