SCA: security update for github.com/fleetdm/fleet/v4 (GHSA-5jvp-m9h4-253h)

medium Tenable Self-Hosted Container Security Plugin ID 438128

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Fleet is open source device management software. In versions prior to 4.80.1, a broken authorization check
 in Fleet’s certificate template deletion API could allow a team administrator to delete certificate
 templates belonging to other teams within the same Fleet instance. Fleet supports certificate templates
 that are scoped to individual teams. In affected versions, the batch deletion endpoint validated
 authorization using a user-supplied team identifier but did not verify that the certificate template IDs
 being deleted actually belonged to that team. As a result, a team administrator could delete certificate
 templates associated with other teams, potentially disrupting certificate-based workflows such as device
 enrollment, Wi-Fi authentication, VPN access, or other certificate-dependent configurations for the
 affected teams. This issue does not allow privilege escalation, access to sensitive data, or compromise of
 Fleet’s control plane. Impact is limited to integrity and availability of certificate templates across
 teams. Version 4.80.1 patches the issue. If an immediate upgrade is not possible, administrators should
 restrict access to certificate template management to trusted users and avoid delegating team
 administrator permissions where not strictly required. (CVE-2026-25963)

Solution

Update the github.com/fleetdm/fleet/v4 library and its related packages to version 4.80.1 or later.
