  3. CVE-2026-29042
Nuclio is a "Serverless" framework for Real-Time Events and Data Processing. Prior to version 1.15.20, the Nuclio Shell Runtime component contains a command injection vulnerability in how it processes user-supplied arguments. When a function is invoked via HTTP, the runtime reads the X-Nuclio-Arguments header and directly incorporates its value into shell commands without any validation or sanitization. This issue has been patched in version 1.15.20.

Summary
  • (es) Nuclio es un 'Serverless' framework para eventos en tiempo real y procesamiento de datos. Antes de la versión 1.15.20, el componente Nuclio Shell Runtime contiene una vulnerabilidad de inyección de comandos en la forma en que procesa los argumentos proporcionados por el usuario. Cuando se invoca una función a través de HTTP, el runtime lee el encabezado X-Nuclio-Arguments e incorpora directamente su valor en comandos de shell sin ninguna validación o saneamiento. Este problema ha sido parcheado en la versión 1.15.20.
