CVE-2026-25807Public exploitNetwork attack vector

Remote code execution via unauthenticated P2P commands

Published Feb 9, 2026 · Updated Feb 9, 2026

Code injection in ZAI Shell before 9.0.3 allows remote attackers to execute system commands through unauthenticated P2P sharing. The P2P handler accepts attacker-controlled command messages on TCP port 5757 and passes approved content to run_command for subprocess execution without Sentinel checks. Reachability requires an active share start session in --no-ai mode, and execution requires the host user to approve the command; successful commands run with that user's privileges.
