## Overview

rclone from v1.56.0 before v1.75.2 contains an information disclosure vulnerability in the WebDAV backend that forwards operator-configured custom credential headers to different hosts on HTTP 3xx redirects. Attackers who control or influence a cross-host redirect can capture headers such as X-Auth-Token set via --webdav-headers and replay them against the original WebDAV service.

## Affected

- `rclone >= 1.56.0 < 1.75.2`

## Remediation

Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
