{"cve":"CVE-2026-71309","nvd":{"published":"2026-08-05T21:16:58.383","modified":"2026-09-09T20:50:00.950","status":"Awaiting Analysis","description":"rclone is a command-line program to sync files and directories to and from different cloud storage providers. From 1.40.0 until 1.75.0, rclone serve restic does not correctly reject URL paths beginning with ../ in cmd/serve/restic/restic.go WithRemote, which accepts a leading parent path and passes it to GET, HEAD, POST, and DELETE handlers for configured backends including WebDAV, FTP, HTTP, Memory, and SFTP. An attacker who can access the REST endpoint may read, create, overwrite, or delete objects outside the path configured by the operator when the operator publishes a backend subdirectory and the backend credential can access parent or sibling objects. This issue is fixed in 1.75.0.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N","score":8.6},"cvss_v3":null,"cwes":["CWE-22"],"references":["https://github.com/rclone/rclone/commit/cc5a189f00efe68ed0ddb32d3237b42549a9f264","https://github.com/rclone/rclone/releases/tag/v1.75.0","https://github.com/rclone/rclone/security/advisories/GHSA-45pq-889g-fcgh","https://github.com/rclone/rclone/security/advisories/GHSA-45pq-889g-fcgh"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:47:10.050265369+00:00"},"epss":{"cve":"CVE-2026-71309","score":0.00459,"percentile":0.39763,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-45pq-889g-fcgh","url":"https://osv.dev/vulnerability/GHSA-45pq-889g-fcgh","summary":"rclone: Incomplete path validation allows backend root escape in serve restic","modified":"2026-09-10T03:51:13.100477661Z","packages":[{"ecosystem":"Go","name":"github.com/rclone/rclone","purl":"pkg:golang/github.com/rclone/rclone","ranges":[">=1.40.0 <1.75.0"],"fixed":["1.75.0"]}]},{"id":"GO-2026-6184","url":"https://osv.dev/vulnerability/GO-2026-6184","summary":"Path traversal in serve restic in github.com/rclone/rclone","modified":"2026-08-18T17:24:07.105270667Z","packages":[{"ecosystem":"Go","name":"github.com/rclone/rclone","purl":"pkg:golang/github.com/rclone/rclone","ranges":["<1.75.0"],"fixed":["1.75.0"]}]}],"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).
