High impact if exploited, but EPSS currently rates exploitation as unlikely (0.46%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
MeshCentral is a full computer management web site. Versions prior to 1.1.21 a cross-site websocket hijacking (CSWSH) vulnerability within the control.ashx endpoint. This component is the primary mechanism used within MeshCentral to perform administrative actions on the server. The vulnerability is exploitable when an attacker is able to convince a victim end-user to click on a malicious link to a page hosting an attacker-controlled site.

Version 1.1.21 contains a patch for this issue.
