Last modified
CVE-2025-40896 is a medium-severity vulnerability rated 6.3/10 on the CVSS scale. The server certificate was not verified when an Arc agent connected to a Guardian or CMC. A malicious actor could perform a man-in-the-middle attack and intercept the communication between the Arc agent and the Guardian or CMC. This could result in theft of the client token and sensitive information (such as assets and alerts), impersonation of the server, or injection of spoofed data (such as false asset information or vulnerabilities) into the Guardian or CMC.. EPSS estimates a 0.11% chance of exploitation in the next 30 days.
