{"id":"BIT-rclone-2026-79783","summary":"rclone before 1.74.4 Privilege Escalation via setuid Metadata","details":"rclone before 1.74.4 fails to mask special permission bits when applying source-supplied mode metadata in the local backend, allowing attackers to set setuid/setgid bits on attacker-controlled files. 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.","aliases":["CVE-2026-79783","GHSA-945v-v9p3-v5xw","GO-2026-6190"],"modified":"2026-09-25T14:25:48.311310825Z","published":"2026-09-25T12:30:16.445Z","database_specific":{"severity":"Low","cpes":["cpe:2.3:a:rclone:rclone:*:*:*:*:*:go:*:*"]},"references":[{"type":"WEB","url":"https://github.com/rclone/rclone/security/advisories/GHSA-945v-v9p3-v5xw"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-79783"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/rclone-before-privilege-escalation-via-setuid-metadata"}],"affected":[{"package":{"name":"rclone","ecosystem":"Bitnami","purl":"pkg:bitnami/rclone"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"1.74.4"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/rclone/BIT-rclone-2026-79783.json"},"severity":[{"type":"CVSS_V4","score":"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/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X"}]}],"schema_version":"1.9.0"}
