In the ConnectWise Automate Agent, communications could be configured to use HTTP instead of HTTPS. In such cases, an on-path threat actor with a man-in-the-middle network position could intercept, modify, or replay agent-server traffic. Additionally, the encryption method used to obfuscate some communications over the HTTP channel is updated in the Automate 2025.9 patch to enforce HTTPS for all agent communications.

Each line links to the index that lists it, never to exploit code. Exploit-DB's "verified" and a Metasploit rank of good or better count as verified; a PoC-in-GitHub entry is a repository's claim.
