CVE-2026-102281

The NestJS framework (prior to versions 11.2.4 and 12.0.2 ) is vulnerable to a remote process termination when using the TCP or RabbitMQ transports. The root cause is that the ServerTCP#handleMessage and ServerRMQ#handleMessage functions pass a client-controlled non-string pattern to JSON.stringi...

n8n Node.js Package < 1.123.76 / 2.0.x < 2.37.7 / 2.38.x < 2.38.2 Multiple Vulnerabilities

The version of the n8n Node.js Package installed on the remote host is less than 1.123.76, or is 2.0.x prior to 2.37.7, or is 2.38.x prior to 2.38.2. It is, therefore, affected by multiple vulnerabilities: - n8n is an open source workflow automation platform. Prior to 1.123.76, 2.37.7, and 2.38.2...
