CVE-2026-57135Public exploitNetwork attack vectorHinoki check available

Network isolation bypass via proxy-only enforcement

Published Sep 15, 2026 · Updated Sep 15, 2026

Protection mechanism failure in PraisonAI 1.2.3 through 1.7.1 allows remote authenticated users to bypass isolation via direct sockets. SandboxExecutor.buildEnv() sets invalid proxy environment variables but establishes no namespace, firewall, socket filter, or other operating-system boundary. Exploitation requires control of a command executed in network-isolated mode and grants access to services and data reachable from the host.
