When copying with metadata preservation from an untrusted remote, attackers can plant a setuid binary that escalates privileges to root if rclone runs as root, or to the service account user otherwise.","state":0,"publishedAt":"2026-08-25T15:16:11.806+00:00","modifiedAt":"2026-08-25T16:11:49.885+00:00","affected":[{"ecosystem":"Vendor product","name":"rclone","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"rclone\",\n                    \"product\": \"rclone\",\n                    \"defaultStatus\": \"unaffected\",\n                    \"packageURL\": \"pkg:golang/github.com/rclone/rclone\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"semver\",\n                            \"lessThan\": \"1.74.4\"\n                        },\n                        {\n                            \"version\": \"1.74.4\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:L/AC:H/AT:P/PR:N/UI:P/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N","score":2,"severity":"LOW"},{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:L/AC:H/PR:N/UI:R/S:U/C:L/I:L/A:N","score":3.6,"severity":"LOW"}],"references":["https://github.com/rclone/rclone/security/advisories/GHSA-945v-v9p3-v5xw","https://www.vulncheck.com/advisories/rclone-before-privilege-escalation-via-setuid-metadata"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-79783","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-79783","identifiers":["CVE-2026-79783"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
