Overview
Affected versions of this package are vulnerable to Improper Authorization through improper validation of the influenceId path parameter in the DELETE endpoint. An attacker can remove arbitrary Traffic Influence Subscriptions by sending a crafted request with an invalid influenceId value and a valid subscriptionId. This is only exploitable if the 5G Service Based Interface (SBI) is accessible to untrusted parties.
