CVE-2026-116196Rclone 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... Executive summary Rclone, an open-source tool for copying and syncing files to cloud storage, has a credential exposure flaw in its Backblaze B2 backend. When a custom download host is configured, the live account authorization token and SSE-C encryption keys can be sent over cleartext or to another host during an HTTP redirect, and the advisory rates it Moderate with a CVSS 3.1 base score of 5.3. The advisory says the fix is to update to v1.75.2, with workarounds that include enforcing HTTPS on the download URL and using least-privilege application keys. Technical summary This is a cleartext transmission of sensitive information issue (CWE-319) in the rclone b2 backend, where the default Go HTTP client follows redirects from the custom --b2-download-url host. A same-host HTTPS-to-HTTP redirect causes the Authorization header to be resent in cleartext, and the SSE-C customer key headers are forwarded to any redirect target host. The advisory lists rclone versions before v1.75.2 and states affected versions as <= v1.75.0 with patched version v1.75.2. The attack vector is Adjacent with high complexity, no privileges or user interaction required, and CVSS 3.1 vector AV:A/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N. The Remediation section says to update to v1.75.1, which conflicts with the patched version v1.75.2 listed elsewhere in the advisory. Workarounds are to enforce an explicit https:// scheme on --b2-download-url, block plaintext redirects at the CDN, unset the download URL, and use scoped application keys. No CVE identifier is stated in the advisory, and no detection guidance or evidence of exploitation in the wild is stated. Summaries are generated by AI from the linked advisory text.
