CVE-2026-73035

npm-check-updates through 23.0.2, fixed in commit b554b84, contains a terminal escape sequence injection vulnerability that allows an attacker to embed arbitrary terminal control characters in a dependency's package.json homepage or repository URL fields. When a developer runs ncu with the --format homepage or --format repo option, unfiltered escape sequences are written directly to the terminal, enabling malicious output manipulation or other terminal-dependent effects.

Summary		(es) npm-check-updates hasta la versión 23.0.2, corregido en el commit b554b84, contiene una vulnerabilidad de inyección de secuencias de escape de terminal que permite a un atacante incrustar caracteres de control de terminal arbitrarios en los campos de URL de la página de inicio o del repositorio del package.json de una dependencia. Cuando un desarrollador ejecuta ncu con la opción --format homepage o --format repo, las secuencias de escape sin filtrar se escriben directamente en la terminal, lo que permite la manipulación maliciosa de la salida u otros efectos dependientes de la terminal.
