SCA: security update for github.com/free5gc/udr (GHSA-4rqf-grm6-vf75)

medium Tenable Self-Hosted Container Security Plugin ID 441577

Description

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

- free5GC is an open-source implementation of the 5G core network. Prior to 4.2.2, free5GC's UDR nudr-dr
DELETE /subscription-data/{ueId}/{servingPlmnId}/ee-subscriptions/{subsId}/amf-subscriptions handler
contains a nil-pointer dereference reachable from a single authenticated request, after one preparatory
authenticated EE-subscription create. The handler checks _, ok =
UESubsData.EeSubscriptionCollection[subsId] and sets a 404 problem-details on the miss path, but then
continues to UESubsData.EeSubscriptionCollection[subsId].AmfSubscriptionInfos -- dereferencing the same
missing entry instead of returning. Gin recovery converts the panic into HTTP 500, but the endpoint
remains repeatedly panicable. This vulnerability is fixed in 4.2.2. (CVE-2026-44323)

Solution

Update the github.com/free5gc/udr library and its related packages to version 1.4.3 or later.
