EUVD-2026-70407

n8n versions before 2.34.1 contain a server-side request forgery vulnerability in the legacy request helper function exposed to Code and Function nodes. The validation logic checks the uri property for SSRF safety while the underlying HTTP client uses the url property when both are present,...

CVE-2026-85172

n8n versions before 2.34.1 contain a server-side request forgery (SSRF) vulnerability in the legacy request helper function exposed to Code and Function nodes. The root cause is a mismatch between validation and execution: the SSRF check inspects the uri property, while the underlying HTTP client...

CVE-2026-85172: Server-Side Request Forgery (SSRF)

EUVD-2026-67809

BISHENG before 2.6.0 contains a remote code execution vulnerability in the workflow runonce endpoint that allows authenticated users to execute arbitrary Python code. Attackers can submit crafted Code node definitions to the POST /api/v1/workflow/runonce endpoint, which executes them with exec...

Prototype Pollution

Overview Affected versions of this package are vulnerable to Prototype Pollution in the JavaScript Code node of @n8n/task-runner, whose hardening pass in js-task-runner.ts froze each global function's prototype only when typeof fn.prototype === 'object', which skips Function.prototype because it ...

CVE-2026-77083

n8n is a workflow automation platform. In versions prior to 1.123.69, 2.33.4, and 2.34.1, the JavaScript Code node's VM sandbox did not freeze the sandbox's Function.prototype, allowing an authenticated user with the ability to create and execute workflows to pollute it from within a Code node...

CVE-2026-77077

n8n versions before 1.123.69, 2.33.4, and 2.34.1 contain a JavaScript task runner VM sandbox escape. The runner's prototype-freezing routine covers globalThis functions but not internal module constructors such as EventEmitter, allowing an authenticated user with Code node access to exploit...

CVE-2026-77083

n8n (workflow automation platform) versions prior to 1.123.69 , 2.33.4 , and 2.34.1 are affected by a sandbox escape in the JavaScript Code node. The VM sandbox did not freeze Function.prototype, allowing an authenticated user with workflow creation and execution privileges to perform prototype p...

CVE-2026-77077

n8n versions before 1.123.69, 2.33.4, and 2.34.1 have a VM sandbox escape in the task runner: the prototype-freezing routine misses internal constructors like EventEmitter, allowing an authenticated user with Code node access to pollute prototypes and execute arbitrary commands. The corruption is...

CVE-2026-77083: Improperly Controlled Modification of Object Prototype Attributes

n8n is a workflow automation platform. In versions prior to 1.123.69, 2.33.4, and 2.34.1, the JavaScript Code node's VM sandbox did not freeze the sandbox's Function.prototype, allowing an authenticated user with the ability to create and execute workflows to pollute it from within a Code node...

CVE-2026-72764

n8n's JavaScript task runner shared a single module cache across all users' Code-node executions. In affected versions before 1.123.67, 2.31.5, and 2.32.1, a user able to run a Code node could poison a cached module and thereby alter other users' Code-node executions on the same runner, affecting...
