CVE-2026-79780Source published Source updated
rclone before v1.75.0 fails to sanitize IBM IAM bearer tokens and SSE-C encryption keys during S3 redirect callbacks, allowing credentials to be preserved across scheme or host changes. Attackers observing network traffic from a trusted endpoint can capture reusable IBM IAM tokens on same-host HTTPS-to-HTTP downgrades or SSE-C keys on cross-origin redirects to access protected S3 objects. A flaw was found in rclone. When rclone interacts with S3 endpoints that issue unsafe redirects, an adjacent network attacker can capture these credentials during HTTPS-to-HTTP downgrades or cross-origin redirects. The impact is constrained by the scope of the captured token and the attacker's access to encrypted objects. Red Hat severity: Moderate — CVSS 5.3…

- Source-reported affected versions
- < 75.0
- Source-reported fixed versions
- No fixed-version detail extracted. This does not mean no fix exists.
- Mitigation guidance
- Until packages are updated, avoid using rclone S3 remotes with IBM IAM bearer tokens or SSE-C customer-provided keys against endpoints or gateways that issue cross-scheme or cross-host redirects. Prefer trusted HTTPS endpoints that do not downgrade or redirect secret-bearing requests.
