Vulnerability Title
rclone: Unvalidated symlink target in local `--links` — arbitrary file write from an untrusted remote
Vulnerability Description
Rclone is a command-line program to sync files and directories to and from different cloud storage providers. Prior to 1.74.4, with -l/--links, rclone serializes symlinks as .rclonelink text objects and recreates them on a local destination without validating the target, allowing an attacker-controlled remote to plant an escaping symlink and cause a following object write to land outside the destination with attacker-chosen contents. This issue is fixed in version 1.74.4.

Vulnerability Title
Rclone 后置链接漏洞
Vulnerability Description
Rclone是Rclone团队开源的一款同步文件到各类云存储服务的命令行工具。 Rclone 1.74.4之前版本存在后置链接漏洞,该漏洞源于在使用-l/--links参数时,将符号链接序列化为.rclonelink文本对象并在本地目标上重新创建时未验证目标,允许攻击者控制的远程服务器植入逃逸符号链接,导致后续对象写入落入目标之外并包含攻击者选择的内容。
