CVE-2019-20057
com.proxyman.NSProxy.HelperTool in Privileged Helper Tool in Proxyman for macOS 1.11.0 and earlier allows an attacker to change the System Proxy and redirect all traffic to an attacker-controlled computer, enabling MITM attacks.
Does this matter?
Lower severity and a low EPSS score (0.50%). Track it; it rarely justifies an emergency change on its own.
