SCA: security update for github.com/fleetdm/fleet, github.com/fleetdm/fleet/v4 (GHSA-4r5r-ccr6-q6f6)

high Tenable Cloud Security Plugin ID 436832

Description

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

 - Fleet is open source device management software. A broken access control issue in versions prior to
 4.78.3, 4.77.1, 4.76.2, 4.75.2, and 4.53.3 allowed authenticated users to access debug and profiling
 endpoints regardless of role. As a result, low-privilege users could view internal server diagnostics and
 trigger resource-intensive profiling operations. Fleet’s debug/pprof endpoints are accessible to any
 authenticated user regardless of role, including the lowest-privilege “Observer” role. This allows low-
 privilege users to access sensitive server internals, including runtime profiling data and in-memory
 application state, and to trigger CPU-intensive profiling operations that could lead to denial of service.
 Versions 4.78.3, 4.77.1, 4.76.2, 4.75.2, and 4.53.3 fix the issue. If an immediate upgrade is not
 possible, users should put the debug/pprof endpoints behind an IP allowlist as a workaround.
