It follows symlinks in this location or uses directories owned by unprivileged users. Because Timeshift also executes scripts under this location, an attacker can attempt to win a race condition to replace scripts created by Timeshift with attacker-controlled scripts. Upon success, an attacker-controlled script is executed with full root privileges. This logic is practically always triggered when Timeshift runs regardless of the command-line arguments used.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H","score":7.0},"cwes":["CWE-59","CWE-362"],"references":["http://www.openwall.com/lists/oss-security/2020/03/06/3","https://bugzilla.suse.com/show_bug.cgi?id=1165802","https://github.com/teejee2008/timeshift/commit/335b3d5398079278b8f7094c77bfd148b315b462","https://github.com/teejee2008/timeshift/releases/tag/v20.03","https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/AAOFXT64CEUMJE3723JDJWTEQWQUCYMD/"],"products":["canonical:ubuntu_linux","fedoraproject:fedora","timeshift_project:timeshift"],"source":"nvd","synced_at":"2026-10-19T21:02:53.949909883+00:00"},"epss":{"cve":"CVE-2020-10174","score":0.0028,"percentile":0.20495,"date":"2026-10-31"},"kev":null,"osv":[],"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).
