Remote Code Execution in PraisonAI codeMode Sandbox

IdentifiersCVE-2026-57141CWE-94

CVE-2026-57141 is a remote code execution vulnerability in PraisonAI's codeMode tool. The issue stems from an insecure sandbox design that executes attacker-influenced JavaScript using new Function() together with a with(sandbox) execution model and a regex-based blocklist intended to restrict dangerous behavior. This approach is bypassable and does not provide effective isolation, allowing untrusted code to escape the intended sandbox boundary and execute in the host Node.js environment. Successful exploitation can result in arbitrary code execution on the underlying system.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation allows an attacker who can influence the code processed by codeMode to obtain full arbitrary code execution on the host system. This can enable reading and modifying files, executing operating system commands, accessing environment variables and embedded credentials, establishing persistence, and facilitating further compromise such as lateral movement from containerized deployments.

Mitigation

If you can’t patch tonight, do this now.

Disable or avoid enabling the vulnerable codeMode tool for agents until a patched version is deployed. Do not depend on the existing blocklist-based sandbox restrictions for security. As a temporary risk-reduction measure, run untrusted code only inside a hardened isolated environment such as a tightly constrained subprocess or sandbox with strict resource controls and a minimal, sanitized runtime environment.

Remediation

Patch, then assume compromise.

Upgrade the praisonai npm package to version 1.7.2 or later. The vulnerable execution model based on new Function(), with(sandbox), and regex blocklisting should be replaced with a properly isolated execution mechanism such as Node.js vm context isolation, isolated-vm, or subprocess-based sandboxing with strong separation from the host environment.
