What is CVE-2020-2146?

The Jenkins Mac Plugin, specifically in versions 1.1.0 and earlier, fails to properly validate SSH host keys when establishing connections with agents. This oversight creates a significant security risk, as it leaves the system exposed to potential man-in-the-middle attacks. Attackers could exploit this vulnerability to intercept communications between the Jenkins server and its agents, leading to unauthorized access and data manipulation.
