CVE-2026-27606

Rollup is a module bundler for JavaScript. Versions prior to 2.80.0, 3.30.0, and 4.59.0 of the Rollup module bundler (specifically v4.x and present in current source) is vulnerable to an Arbitrary File Write via Path Traversal. Insecure file name sanitization in the core engine allows an attacker to control output filenames (e.g., via CLI named inputs, manual chunk aliases, or malicious plugins) and use traversal sequences (`../`) to overwrite files anywhere on the host filesystem that the build process has permissions for. This can lead to persistent Remote Code Execution (RCE) by overwriting critical system or user configuration files. Versions 2.80.0, 3.30.0, and 4.59.0 contain a patch for the issue.

Summary
  • (es) Rollup es un empaquetador de módulos para JavaScript. Las versiones anteriores a la 2.80.0, 3.30.0 y 4.59.0 del empaquetador de módulos Rollup (específicamente v4.x y presente en el código fuente actual) es vulnerable a una escritura de archivo arbitraria mediante salto de ruta. La sanitización insegura de nombres de archivo en el motor principal permite a un atacante controlar los nombres de archivo de salida (por ejemplo, mediante entradas con nombre de CLI, alias de fragmentos manuales o plugins maliciosos) y usar secuencias de salto ('../') para sobrescribir archivos en cualquier lugar del sistema de archivos del host para el que el proceso de compilación tenga permisos. Esto puede conducir a una ejecución remota de código (RCE) persistente al sobrescribir archivos de configuración críticos del sistema o del usuario. Las versiones 2.80.0, 3.30.0 y 4.59.0 contienen un parche para el problema.
