CVE-2026-57135

PraisonAI SandboxExecutor network-isolated mode does not block non-proxy-aware network clients

Published Sep 15, 2026 CVSS 3.1 · 7.6 High EPSS < 1% KEV · Not listed
Description
PraisonAI is a multi-agent teams system. From 1.2.3 until 1.7.2, SandboxExecutor network-isolated mode in src/praisonai-ts/src/cli/features/sandbox-executor.ts uses buildEnv() only to inject invalid http_proxy and https_proxy environment variables and does not establish an operating-system network boundary. Programs that ignore those proxy variables can open sockets directly, allowing supposedly isolated commands to reach localhost, internal services, cloud metadata, or external hosts and potentially exfiltrate data. An initial remediation was released in version 1.7.2.
