CVE-2026-77080 n8n before 1.123.69 Arbitrary File Read and Write via Snowflake

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-2026-77080

The Snowflake node in n8n passes free-form Execute Query input, including client-side commands, directly to the Snowflake SDK without applying n8n's file-access restrictions, enabling arbitrary file read and write on the n8n host. Affected versions: n8n before 1.123.69, 2.x before 2.33.4, and 2.3...

CVE-2026-77077 n8n before 1.123.69 Remote Code Execution via EventEmitter Prototype Pollution

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-2026-77076 n8n before 1.123.69 Credential Leak via GraphQL Node Error

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-2026-77077

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-2026-77076

n8n versions before 1.123.69, 2.33.4, and 2.34.1 have a GraphQL node flaw where connection-level errors are re-thrown with raw HTTP client error data containing decrypted credential secrets, persisted in execution run data readable by any authenticated user. CVSS 7.1 HIGH. Patch versions are 1.12...
