CVE-2022-22787
This issue could be used in a more sophisticated attack to trick an unsuspecting users client to connect to a malicious server when attempting to use Zoom services.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (3.63%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
