Quick assessment

Affected
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是Rclone团队开源的一个支持多协议的数据同步工具。 Rclone 1.51.0版本至1.75.0之前版本存在路径遍历漏洞，该漏洞源于本地后端backend/local/local.go依赖可配置的文件名编码器防止远程文件名数据成为操作系统路径语法，但某些编码会将全角点号组件或反斜杠形式解码为父目录组件，可能导致攻击者控制的源对象在所选目标目录之外创建或覆盖文件。

Vulnerability Title
rclone: Local Encoding Path Traversal
Source: CVE Program / CVE List V5
Vulnerability Description
rclone is a command-line program to sync files and directories to and from different cloud storage providers. From v1.51.0 until v1.75.0, the local backend in backend/local/local.go relies on the configurable filename encoder to prevent remote filename data from becoming operating-system path syntax, so a local destination using Slash, None, Raw, or on Windows an encoding that preserves backslash can decode a standard-encoded fullwidth dot-dot component or native backslash form into an actual parent-directory component before filepath.Join resolves it outside the configured local root, allowing an attacker-controlled source object to create or overwrite files outside the selected destination directory as the rclone process. This issue is fixed in v1.75.0.
