SCA: security update for github.com/rclone/rclone (GHSA-xwwr-4h3p-r22c)

critical Tenable Self-Hosted Container Security Plugin ID 447926

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 1.75.1, rclone serve s3 configured with --auth-proxy but without --auth-key allows
authPairMiddleware to register any client-chosen accessKeyID with an empty ws.s3Secret. gofakes3 then
verifies the request’s SigV4 signature against that same empty secret, while Server.auth passes the access
key identifier as both the user and authentication value to the proxy without an independent per-identity
secret. An unauthenticated network attacker can therefore choose an arbitrary access key, sign with an
empty secret, and reach whatever backend the auth-proxy script resolves for that identity. This issue is
fixed in version 1.75.1. (CVE-2026-88018)

Solution

Update the github.com/rclone/rclone library and its related packages to version 1.75.1 or later.
