Overview
Affected versions of this package are vulnerable to Improper Check for Unusual or Exceptional Conditions in the provisioningOfTrafficRoutingInfo function when a POST request to the app-session creation endpoint includes suppFeat set to "1" and a medComponents entry with afAppId present but omits AfRoutReq. An attacker can cause the server to panic and return an HTTP 500 error by sending a crafted authenticated request that triggers a nil pointer dereference. This is only exploitable if the attacker possesses a valid npcf-policyauthorization OAuth2 access token.
