CVE-2026-53785

rsync before 3.5.0 contains a path traversal vulnerability that allows a malicious sender to write files outside the intended destination directory tree by crafting relative paths with symlink components in --relative mode. The make_path() function follows symlinks pointing outside the destination tree while creating intermediate directories without verifying that created paths remain within the destination boundary, enabling arbitrary file writes on the receiver's filesystem.

Summary		(es) rsync antes de 3.5.0 contiene una vulnerabilidad de salto de ruta que permite a un remitente malicioso escribir archivos fuera del árbol de directorios de destino previsto al crear rutas relativas con componentes de enlace simbólico en modo --relative. La función make_path() sigue enlaces simbólicos que apuntan fuera del árbol de destino mientras crea directorios intermedios sin verificar que las rutas creadas permanezcan dentro del límite de destino, lo que permite escrituras de archivos arbitrarias en el sistema de archivos del receptor.
