SCA: security update for github.com/fleetdm/fleet/v4 (GHSA-99hj-44vg-hfcp)

high Tenable Cloud Security Plugin ID 439341

Description

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

 - Fleet is open source device management software. Prior to 4.81.0, Fleet contained multiple unauthenticated
 HTTP endpoints that read request bodies without enforcing a size limit. An unauthenticated attacker could
 exploit this behavior by sending large or repeated HTTP payloads, causing excessive memory allocation and
 resulting in a denial-of-service (DoS) condition. Version 4.81.0 patches the issue. (CVE-2026-26061)

Solution

Update the github.com/fleetdm/fleet/v4 library and its related packages to version 4.43.5-0.20260113202849-bbc1aef2987d or later.
