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-2026-72764

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...
