Описание
A flaw in Node.js TLS hostname handling can cause Embedded-nul hostnames can lead to silent authority rebinding due to c-string truncation in resolver bindings.
This vulnerability affects all supported release lines: Node.js 22, Node.js 24, and Node.js 26.
A flaw was found in Node.js. This vulnerability in the TLS (Transport Layer Security) hostname handling allows embedded null characters in hostnames. This can lead to silent authority rebinding, potentially enabling an attacker to redirect network traffic to an unintended server and disclose sensitive information.
