CVE-2026-52875

Full vulnerability record from the local CVENow database.

Description

Streambert is a cross-platform Electron Desktop App to stream and download video content. Prior to 2.6.0, the perform-scheduled-backup IPC handler in src/ipc/storage.js takes settings.path from a renderer-supplied object and uses the resulting directory for fs.mkdirSync, fs.writeFileSync, fs.readdirSync, and fs.unlinkSync operations without checking that it is inside an authorized backup location. A compromised renderer can choose an absolute path or a relative traversal path to create directories and write a streambert-backup-[timestamp].json file containing renderer-controlled data. The pruning loop can also delete files in that directory whose names begin with streambert-backup- and end with .json. This vulnerability is fixed in 2.6.0.

      "value": "Streambert es una aplicación de escritorio Electron multiplataforma para transmitir y descargar contenido de video. Antes de la versión 2.6.0, el gestor IPC perform-scheduled-backup en src/ipc/storage.js toma settings.path de un objeto proporcionado por el renderizador y utiliza el directorio resultante para operaciones de fs.mkdirSync, fs.writeFileSync, fs.readdirSync y fs.unlinkSync sin verificar que esté dentro de una ubicación de copia de seguridad autorizada. Un renderizador comprometido puede elegir una ruta absoluta o una ruta de recorrido relativa para crear directorios y escribir un archivo streambert-backup-[timestamp].json que contiene datos controlados por el renderizador. El bucle de poda también puede eliminar archivos en ese directorio cuyos nombres comienzan con streambert-backup- y terminan con .json. Esta vulnerabilidad se corrige en la versión 2.6.0."
