rclone rclone
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.
rclone 在 1.75.1 之前的版本未能将来自服务器和第三方列表响应中的对象名称限制在所列目录内，从而允许对象名称中出现路径遍历序列。攻击者可以构造包含正斜杠和父目录引用的特殊名称，可能会在目标根目录之外写入文件；不过，本地后端当前的下游防护机制目前会阻止文件实际“逃逸”到根目录之外。

Vulnerability Title
rclone before 1.75.1 Path Traversal via Directory Listing Names
Source: CVE Program / CVE List V5
Vulnerability Description
rclone before 1.75.1 fails to confine names from server and third-party listing responses to the listed directory, allowing path traversal sequences in object names. Attackers can craft special names containing forward slashes and parent directory references to potentially write outside the destination root, though downstream protections in the local backend currently block actual file escape.
