ConnectWise has released a security update for ConnectWise Automate™ that addresses a behavior in the ConnectWise Automate Solution Center where certain client-to-server communications could occur without transport-layer encryption. This could allow network‑based interception of Solution Center traffic in Automate deployments. The issue has been resolved in Automate 2026.4 by enforcing secure communication for affected Solution Center connections.

The ConnectWise Automate Agent does not fully verify the authenticity of files downloaded from the server, such as updates, dependencies, and integrations. This creates a risk where an on-path attacker could perform a man-in-the-middle attack and substitute malicious files for legitimate ones by impersonating a legitimate server. This risk is mitigated when HTTPS is enforced and is related to CVE-2025-11492.

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.
