{"id":"CVE-2026-88014","summary":"rclone archive/zip: Zip Slip via unsanitized zip entry names lets a malicious archive escape its own namespace","details":"rclone is a command-line program to sync files and directories to and from different cloud storage providers. From 1.72.0 until 1.75.1, the archive ZIP backend method (*Fs).readZip in backend/archive/zip/zip.go accepts archive/zip.File.Name values from an untrusted central directory and exposes cleaned entry names without ensuring that they remain inside the archive namespace. Entries such as ../../etc/cron.d/evil can survive path.Clean and become Object.Remote() values that fs/sync and fs/operations use as destination-relative paths, allowing rclone copy or sync to write outside the selected destination on backends that do not independently confine the path. The non-empty root check also used strings.HasPrefix without a path boundary, so root foo could incorrectly include sibling foobar entries. This issue is fixed in version 1.75.1.","aliases":["GHSA-66hp-wgxq-6f5q"],"modified":"2026-09-12T03:47:21.373144188Z","published":"2026-09-10T15:48:32.953Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/88xxx/CVE-2026-88014.json","cna_assigner":"GitHub_M","cwe_ids":["CWE-22"]},"references":[{"type":"WEB","url":"https://github.com/rclone/rclone/releases/tag/v1.75.1"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/88xxx/CVE-2026-88014.json"},{"type":"ADVISORY","url":"https://github.com/rclone/rclone/security/advisories/GHSA-66hp-wgxq-6f5q"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-88014"},{"type":"FIX","url":"https://github.com/rclone/rclone/commit/5dae3adbf571a6cd9ba501eb47397a7e871e1ae0"},{"type":"FIX","url":"https://github.com/rclone/rclone/commit/6507e13d5a83789f500af96d7188c302c9d74d98"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/rclone/rclone","events":[{"introduced":"38ab3dd5b1df946aecf5bd085c671c86f46f68eb"},{"fixed":"5dae3adbf571a6cd9ba501eb47397a7e871e1ae0"},{"fixed":"6507e13d5a83789f500af96d7188c302c9d74d98"},{"fixed":"687d264b689b8c49a67e2e52a8a5e0caa01c04ce"}],"database_specific":{"extracted_events":[{"introduced":"1.72.0"},{"fixed":"1.75.1"}],"source":["AFFECTED_FIELD","REFERENCES"]}}],"versions":["v1.75.0","v1.74.0","v1.73.0","v1.72.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-88014.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:C/C:N/I:H/A:N"}]}
