CVE-2026-70460

rsync 2.3.3 before 3.5.0 contains a path traversal vulnerability that allows a malicious sender to escape the module root by exploiting symlinks within the module file tree when using --partial-dir or --backup-dir options. Attackers with write access to place a symlink under the module root, or who can exploit a pre-existing trusted symlink, can direct file writes to locations outside the intended module root, achieving arbitrary file write relative to the module root parent.

Summary		(es) rsync 2.3.3 anterior a 3.5.0 contiene una vulnerabilidad de salto de ruta que permite a un remitente malicioso escapar de la raíz del módulo al explotar enlaces simbólicos dentro del árbol de archivos del módulo cuando se usan las opciones --partial-dir o --backup-dir. Atacantes con acceso de escritura para colocar un enlace simbólico bajo la raíz del módulo, o que pueden explotar un enlace simbólico de confianza preexistente, pueden dirigir escrituras de archivos a ubicaciones fuera de la raíz del módulo prevista, logrando una escritura de archivo arbitraria relativa al padre de la raíz del módulo.
