HIGHPre-NVD 8.68.6—
EchelonGraph scoreMEDIUM confidence

This high-severity CVE scores 8.6 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.3%, top 76% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

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.
