SCA: security update for github.com/free5gc/nrf (GHSA-f8qv-7x5w-qr48)

high Tenable Self-Hosted Container Security Plugin ID 441572

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 NRF root SBI
 endpoint POST /oauth2/token contains a parser-level type-confusion bug family. The handler in
 NFs/nrf/internal/sbi/api_accesstoken.go reflects over models.NrfAccessTokenAccessTokenReq, special-cases
 only plain string and NrfNfManagementNfType fields, and treats every other field as if it were a single
 models.PlmnId. The parsed *models.PlmnId is then assigned with reflect.Value.Set() to whichever field name
 the attacker put in the form body, which panics whenever the destination field's real type is incompatible
 (slice, different struct, primitive). Gin recovery converts each panic into HTTP 500, but the endpoint
 remains remotely panicable from a single unauthenticated form-encoded request and is repeatedly
 triggerable. This vulnerability is fixed in 4.2.2. (CVE-2026-44325)

Solution

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