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-2026-77076: Generation of Error Message Containing Sensitive Information

n8n versions before 1.123.69, 2.33.4, and 2.34.1 contain an information disclosure vulnerability in the GraphQL node. When a GraphQL request fails at the connection level, the node re-throws the underlying HTTP client error unchanged instead of wrapping it in n8n's standard error type. That error...

CVE-2026-77080: Improper Neutralization of Special Elements used in an OS Command

n8n before 1.123.69, 2.x before 2.33.4, and 2.34.x before 2.34.1 contain an arbitrary file read and write vulnerability in the Snowflake node, which passes free-form Execute Query input, including client-side commands, directly to the Snowflake SDK without applying n8n's file-access restrictions...

CVE-2026-77072: Improper Neutralization of Input During Web Page Generation

n8n before 1.123.69, 2.33.4, and 2.34.1 contains a stored cross-site scripting vulnerability in the Form node's completion page. The completion page applied its sandboxing Content-Security-Policy only when respondWith was not set to 'redirect', but responseText was always rendered as raw HTML. An...

CVE-2026-77070: Improper Neutralization of Special Elements in Data Query Logic

n8n before 1.123.69, 2.33.4, and 2.34.1 contains a NoSQL injection vulnerability in the MongoDB node's Find, Delete, and Aggregate operations, which parse the Query parameter as JSON after expression resolution without sanitizing MongoDB operators. An attacker who can influence the resolved query...

CVE-2026-77068: Improper Limitation of a Pathname to a Restricted Directory

n8n before 2.33.4 and 2.34.x before 2.34.1 contain a remote code execution vulnerability in the @n8n/workflow-sdk node-schema loader used for MCP node-schema loading. The loader derives a node's schema module path directly from the attacker-supplied node type string without validating...
