    "summary": "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.",
