Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Versions of rclone before 1.75.0 are affected. When the WebDAV backend follows a same-host redirect from HTTPS to plaintext HTTP, it can resend Basic authorization and configured Cookie headers over the unencrypted hop. An attacker who can observe that plaintext traffic, such as an on-path actor, could reuse the captured credentials for the account's WebDAV access. Upgrade to rclone 1.75.0 or later.
