SCA: security update for github.com/free5gc/udr (GHSA-6gxq-gpr8-xgjp)

medium Tenable Self-Hosted Container Security Plugin ID 446765

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. In 4.2.3 and earlier,
 HandleCreateEeSubscriptions and HandleQueryeesubscriptions in free5gc/udr
 internal/sbi/api_datarepository.go validate the ueId path value with a regular expression whose final .+
 alternative accepts every non-empty string instead of restricting identifiers to supported SUPI and GPSI
 formats. An actor with network reachability to the UDR SBI can submit a non-3GPP identifier to /nudr-
 dr/v2/subscription-data/{ueId}/context-data/ee-subscriptions, causing the identifier to pass validation
 and enter the normal create or query flow. The advisory does not independently establish whether
 authentication is required. Invalid identifiers can be persisted and retrieved as subscription records,
 enabling unauthorized data creation, UDR namespace pollution, persistent subscriber-metadata corruption,
 and interference with downstream components that trust stored identifiers to use valid 3GPP formats. The
 exposure is most relevant in lab, test, or loosely segmented service-based-interface deployments where
 direct UDR access is possible. (CVE-2026-47780)
