CVSS v3 base score: 6.5, MEDIUM (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:N)

Weakness information:
cwe_id: CWE-940
cwe_name: Improper Verification of Source of a Communication Channel
description: The product establishes a communication channel to handle an incoming request that has been initiated by an actor, but it does not properly verify that the request is coming from the expected origin.
extended_description: When an attacker can successfully establish a communication channel from an untrusted origin, the attacker may be able to gain privileges and access unexpected functionality.
