NVD Description

Note: Versions mentioned in the description apply only to the upstream rclone package and not the rclone package as distributed by Debian. See How to fix? for Debian:unstable relevant fixed versions and status.

Rclone before v1.75.2 contains a credential exposure vulnerability in the b2 backend that leaks the live account Authorization token and SSE-C keys on HTTP redirects from --b2-download-url hosts. Attackers can observe a same-host HTTPS-to-HTTP downgrade redirect to capture the cleartext B2 token, or receive cross-host redirects disclosing SSE-C customer encryption keys.
