Echo: rclone: security update to 1.75.2-1

medium Tenable Cloud Security Plugin ID 478375

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - rclone is a command-line program to sync files and directories to and from different cloud storage
 providers. Prior to 1.75.0, the shared HTTP CONNECT helper in lib/proxy/http.go parses proxy CONNECT
 responses with http.ReadResponse over an unrestricted buffered reader, allowing a malicious or compromised
 configured proxy, or an active on-path actor controlling a plaintext HTTP proxy hop, to send oversized
 headers that grow memory until the rclone process fails. The affected helper is used by FTP and SFTP proxy
 connections, and SFTP reaches the parser before SSH server authentication, so target host key validation
 does not constrain a malicious proxy. This issue is fixed in 1.75.0. (CVE-2026-71310)

Solution

Update the rclone library and its related packages to version 1.75.2-1 or later.
