SCA: security update for github.com/free5gc/udm (GHSA-5rvc-5cwx-g5x8)

high Tenable Cloud Security Plugin ID 438990

Description

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

- Free5GC is an open-source Linux Foundation project for 5th generation (5G) mobile core networks. In
versions prior to 1.4.2, the UDM incorrectly converts a downstream 400 Bad Request (from UDR) into a 500
Internal Server Error when handling PATCH requests with an empty supi path parameter. Additionally, the
UDM incorrectly translates the PATCH method to PUT when forwarding to UDR, indicating a deeper
architectural issue. This leaks internal error handling behavior, making it difficult for clients to
distinguish between client-side errors and server-side failures. The issue has been patched in version
1.4.2. (CVE-2026-33192)

Solution

Update the github.com/free5gc/udm library and its related packages to version 1.4.2 or later.
