SCA: security update for github.com/henrygd/beszel (GHSA-5f5r-95pg-xrpm)

low Tenable Cloud Security Plugin ID 440148

Description

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

 - Beszel is a server monitoring platform. Prior to 0.18.7, some API endpoints in the Beszel hub accept a
 user-supplied system ID and proceed without further checks that the user should have access to that
 system. As a result, any authenticated user can access these routes for any system if they know the
 system's ID. System IDs are random 15 character alphanumeric strings, and are not exposed to all users.
 However, it is theoretically possible for an authenticated user to enumerate a valid system ID via web
 API. To use the containers endpoints, the user would also need to enumerate a container ID, which is 12
 digit hexadecimal string. This vulnerability is fixed in 0.18.7. (CVE-2026-40077)

Solution

Update the github.com/henrygd/beszel library and its related packages to version 0.18.7 or later.
