Summary

PraisonAI from 4.5.110 before 4.6.61 has a flaw in SandlockSandbox. When the optional sandlock module reports that Landlock is unavailable, execute() silently falls back to a subprocess backend that does not enforce the configured filesystem and network limits (CWE-693). A local user with low privileges can run code that reads files outside the allowed path and opens network connections despite network=False.

Description from the CNA

PraisonAI is a multi-agent teams system. From version 4.5.110 to before version 4.6.61, praisonai.sandbox.SandlockSandbox is documented and implemented as the kernel-enforced sandbox backend for untrusted code. Its SandboxConfig.native() path lets callers configure allowed filesystem paths and network=False. On systems where the optional sandlock module imports but reports that Landlock is unavailable, SandlockSandbox.execute() and run_command() do not fail closed. They silently fall back to SubprocessSandbox(self.config). That fallback keeps the same high-level native policy object but does not enforce the native filesystem or network boundary during code execution. A sandboxed payload can read files outside the configured allowed path and open network connections despite network=False. This issue has been patched in version 4.6.61.
