Expression-Sandbox-Escape-Simulation-Lab

🧪 Expression Sandbox Escape – Simulation Lab A minimal experimental environment for demonstrating JavaScript expression sandbox escape and patch evolution. Through multiple versions of the sandbox, it implements the progression from: Fully escapable → patching this → then patching destructuring...

EUVD-2026-70400

n8n versions before 2.36.2 contain an expression sandbox bypass vulnerability where free identifiers in spread, computed-key, switch-case, or class-extension positions resolve against process globals. Authenticated users with workflow-edit permission can mutate host objects through expression...

CVE-2026-85169: Improper Control of Generation of Code

n8n versions before 1.123.73, 2.35.4, and 2.36.2 contain an expression sandbox escape in the $fromAI handler. $fromAI resolved a caller-supplied placeholder name without requiring it to be an own property and admitted reserved keys; against a primitive input value it returned a live host-prototyp...

CVE-2026-85165: Improper Neutralization of Directives in Dynamically Evaluated Code

n8n versions before 2.36.2 contain an expression sandbox bypass vulnerability where free identifiers in spread, computed-key, switch-case, or class-extension positions resolve against process globals. Authenticated users with workflow-edit permission can mutate host objects through expression...

CVE-2026-72765 n8n before 2.32.1 Remote Code Execution via Expression Sandbox Escape

n8n before 2.31.5 and before 2.32.1 contain a sandbox escape vulnerability in expression evaluation. An authenticated user with permission to create or modify workflows can craft expressions using arrow-function bodies to bypass the expression sandbox, triggering system command execution on the...

EUVD-2026-54519

Nexus Repository 3 did not fully sandbox JEXL expressions used in Content Selectors. An account holding the nexus:selectors:create permission could construct an expression that read Java object properties not intended to be exposed to the expression engine, disclosing internal JVM class metadata...

GHSA-GV7G-JM28-CR3M n8n: Expression sandbox escape via arrow-function bodies enabling command execution

Impact An authenticated user with permission to create or modify workflows could abuse crafted expressions using arrow functions to bypass the expression sandbox, triggering unintended system command execution on the host running n8n. Patches The issue has been fixed in n8n versions 2.31.5 and...

CVE-2026-27577

CVE-2026-27577 concerns n8n’s expression evaluation in workflow parameters, enabling remote code execution when an authenticated user with workflow edit rights crafts expressions. The issue is the expression sandbox escape leading to unintended host command execution. Affected releases are before...

CVE-2026-27577 n8n: Expression Sandbox Escape Leads to RCE

n8n is an open source workflow automation platform. Prior to versions 2.10.1, 2.9.3, and 1.123.22, additional exploits in the expression evaluation of n8n have been identified and patched following CVE-2025-68613. An authenticated user with permission to create or modify workflows could abuse...

n8n: Expression Sandbox Escape Leads to RCE

Impact Additional exploits in the expression evaluation of n8n have been identified and patched following CVE-2025-68613. An authenticated user with permission to create or modify workflows could abuse crafted expressions in workflow parameters to trigger unintended system command execution on th...

CVE-2026-1470

CVE-2026-1470 affects n8n: a critical Remote Code Execution in the workflow Expression evaluation system where expressions from authenticated users are evaluated in a runtime context that isn’t sufficiently isolated. This allows an authenticated attacker to execute arbitrary code with the n8n pro...

CVE-2026-1470 Authenticated users can bypass the Expression sandbox mechanism to achieve full remote code execution on n8n’s main node.

n8n contains a critical Remote Code Execution RCE vulnerability in its workflow Expression evaluation system. Expressions supplied by authenticated users during workflow configuration may be evaluated in an execution context that is not sufficiently isolated from the underlying runtime. An...
