{"cve":"CVE-2026-88013","nvd":{"published":"2026-09-10T16:18:08.203","modified":"2026-09-23T20:28:10.653","status":"Analyzed","description":"rclone is a command-line program to sync files and directories to and from different cloud storage providers. From 1.49.0 until 1.75.1, the HTTP backend attaches headers configured through --http-headers or headers= to requests in backend/http/http.go, while its fshttp.NewClient client follows redirects without a backend-specific http.Client.CheckRedirect policy. A configured remote that redirects to another host can therefore cause custom secrets such as X-Api-Key to be resent to that untrusted destination, and a same-host HTTPS-to-HTTP redirect can expose Authorization or Cookie headers in cleartext. Listing, stat, download, mount, and serve operations can trigger the leak during normal use. This issue is fixed in version 1.75.1.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","score":5.3},"cwes":["CWE-200","CWE-319","CWE-522"],"references":["https://github.com/rclone/rclone/commit/22859b7e696cea3c563c6ba04c6b7f91f74456b4","https://github.com/rclone/rclone/commit/79fbc0842f74e02cb84f0e3e7261d169983c8831","https://github.com/rclone/rclone/commit/925fb4fb21eb25e75cd1b64fdd17ded857784bfc","https://github.com/rclone/rclone/releases/tag/v1.75.1","https://github.com/rclone/rclone/security/advisories/GHSA-486v-q2wf-fp2r"],"products":["rclone:rclone"],"source":"nvd","synced_at":"2026-10-19T22:52:53.108888569+00:00"},"epss":{"cve":"CVE-2026-88013","score":0.00187,"percentile":0.08306,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-486v-q2wf-fp2r","url":"https://osv.dev/vulnerability/GHSA-486v-q2wf-fp2r","summary":"rclone: http backend forwards custom/auth headers to a different host on redirect","modified":"2026-09-19T09:25:46.964765936Z","packages":[{"ecosystem":"Go","name":"github.com/rclone/rclone","purl":"pkg:golang/github.com/rclone/rclone","ranges":[">=1.49.0 <1.75.1"],"fixed":["1.75.1"]}]},{"id":"GO-2026-6463","url":"https://osv.dev/vulnerability/GO-2026-6463","summary":"rclone: http backend forwards custom/auth headers to a different host on redirect in github.com/rclone/rclone","modified":"2026-09-19T09:25:46.964765936Z","packages":[{"ecosystem":"Go","name":"github.com/rclone/rclone","purl":"pkg:golang/github.com/rclone/rclone","ranges":[">=1.49.0 <1.75.1"],"fixed":["1.75.1"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
