Upgrade github.com/free5gc/bsf/internal/sbi/processor to version 1.0.2 or higher.
Overview
Affected versions of this package are vulnerable to Missing Synchronization through unsynchronized access to the Subscriptions map in the PUT /nbsf-management/v1/subscriptions/{subId} handler. An attacker can cause the process to terminate unexpectedly by sending concurrent authenticated PUT requests with unique subId values, leading to a fatal runtime error and complete loss of service availability. This is only exploitable if the attacker possesses a valid nbsf-management OAuth2 access token.
