CVE-2026-57136

PraisonAI SandboxExecutor allowedCommands bypass via shell chaining

Published: Sep 15, 2026Updated: Sep 15, 2026 Sources: CVE List NVDCWE-78

8.8HIGH

Description

PraisonAI is a multi-agent teams system. From 1.2.3 until 1.7.2, CommandValidator in src/praisonai-ts/src/cli/features/sandbox-executor.ts validates only the first whitespace-delimited executable against allowedCommands, then SandboxExecutor passes the complete command string to sh -c. A command beginning with an allowed executable can append a non-allowlisted command through shell metacharacters, causing arbitrary commands to run with the PraisonAI process privileges. This issue is fixed in version 1.7.2.
