CVE Summary Severity CVSS EPSS Priority Signals
CVE-2026-78417 Intercepted VNC sessions in Devolutions Remote Desktop Manager are possible because the IronVNC client automatically accepts the server's RSA key without verification during RSA-AES authentication, leaving an on-path attacker able to substitute their own key and relay tampered traffic. Both the 2026.2.x branch (up to 2026.2.17.0) and the 2026.1.x branch (up to 2026.1.24.0) are affected. No public exploit exists and EPSS sits at 0.11% (1st percentile), but the attack requires only network positioning and a user-initiated VNC session, making it a realistic threat on untrusted or adversary-adjacent networks.
