SCA: security update for github.com/free5gc/smf (GHSA-3258-qmv8-frp3)

critical Tenable Self-Hosted Container Security Plugin ID 441580

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 SMF mounts the
 UPI management route group without OAuth2/bearer-token authorization middleware. A network attacker who
 can reach SMF on the SBI can hit UPI endpoints with no Authorization header at all, and the requests reach
 the SMF business handlers. In the running Docker lab this was directly demonstrated for read (GET
 /upi/v1/upNodesLinks), write (POST /upi/v1/upNodesLinks with attacker-controlled UP-node and link
 payload), and delete (DELETE /upi/v1/upNodesLinks/{nodeID}) operations. This vulnerability is fixed in
 4.2.2. (CVE-2026-44329)

Solution

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