CVE-2026-44217

sse-channel is an SSE-implementation which can be used to any node.js http request/response stream. Prior to 4.0.1, implementations that allow user-provided values to be passed to event, retry or id fields are susceptible to event spoofing, where an attacker could inject arbitrary messages into the stream. This vulnerability is fixed in 4.0.1.

Summary		(es) sse-channel es una implementación de SSE que puede ser utilizada con cualquier flujo de solicitud/respuesta HTTP de node.js. Antes de la versión 4.0.1, las implementaciones que permiten que valores proporcionados por el usuario se pasen a los campos event, retry o id son susceptibles a la suplantación de eventos, donde un atacante podría inyectar mensajes arbitrarios en el flujo. Esta vulnerabilidad está corregida en la versión 4.0.1.
