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: 0.5% (37th percentile of EPSS-scored CVEs). 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).

A fix is available — apply it.

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.

Exploitation public PoC (CISA Vulnrichment) · Automatable no (CISA Vulnrichment) · Technical impact total (CISA Vulnrichment). Mission impact is CISA's Mission & Well-being decision point, and only you can judge it: high means the affected system is essential to your organisation's mission, or its compromise could cause irreversible harm to people.
