Critical (9.3). EPSS 0.1% chance of exploitation in the next 30 days. Fixed in github.com/rclone/rclone 1.74.4.
rclone before 1.74.4 fails to strip the X-Amz-Security-Token header when an S3 redirect changes scheme from HTTPS to HTTP on the same host. Attackers can intercept plaintext HTTP traffic to capture AWS STS session tokens sent in request headers.
