Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-88016 exists.\n\nAffected packages and fixed versions:\n- github.com/rclone/rclone (Go): affected all versions; fixed in 1.75.1\n- github.com/rclone/rclone (Go): affected all versions; fixed in 1.75.1\n- github.com/rclone/rclone (Go): affected all versions; fixed in 1.75.1\n- rclone (Bitnami): affected all versions; fixed in 1.75.1\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-88016/ (Markdown: https://insights.sbomify.com/CVE-2026-88016/index.md)","id":"CVE-2026-88016","markdown":"https://insights.sbomify.com/CVE-2026-88016/index.md","name":"CVE-2026-88016","record":{"aliases":["BIT-rclone-2026-88016","DEBIAN-CVE-2026-88016","GHSA-f8g7-2xjc-7mfh","GO-2026-6459","MINI-59cc-cq32-748j","MINI-7fg6-4mmr-ph8x","MINI-9f3r-p7q2-fxfq","MINI-cvv5-x3v6-qw7v","MINI-jmh9-q294-gr7v","MINI-v23c-v2rx-599p","MINI-wvc4-3rp5-5gvw","MINI-x6rv-56fg-qg8g","UBUNTU-CVE-2026-88016"],"analysis":{"component_type":"developer_tool","fix_type":"upgrade","impacts":["data_modify","privilege_escalation"],"network_reachable":"yes","non_default_config":true,"product_category":"rclone file sync tool","requires_auth":"low_privilege","summary":"An attacker can use planted symlinks to modify permissions or ownership of files outside the destination directory when using specific rclone flags.","user_interaction":"required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"rclone","vendor":"rclone"}],"cvss":{"score":7.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:C/C:L/I:H/A:L","version":"3.1"},"cwes":[{"id":"CWE-59","name":"Improper Link Resolution Before File Access"},{"id":"CWE-281","name":"Improper Preservation of Permissions"}],"description":"rclone is a command-line program to sync files and directories to and from different cloud storage providers. Prior to 1.75.1, when backend/local runs with --links, a source .rclonelink object can plant a symlink in the destination and later directory metadata is applied through that path. MkdirMetadata, writeMetadataToFile, and setTimes operate when Directory.translatedLink=false, so os.Chown, os.Chmod, os.Chtimes, and birth-time handling can bypass os.Root confinement and follow the symlink. An attacker controlling source contents can therefore apply selected ownership, permissions, modification times, or birth times to a file or directory outside the destination, with --metadata required for chmod and chown while modification time is applied by the normal directory workflow. This issue is fixed in version 1.75.1.","ecosystems":["Bitnami","Go"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":true,"headline":"rclone: Directory metadata (chmod/chown/chtimes) applied through a planted symlink in rclone local --links escapes the destination","id":"CVE-2026-88016","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":null,"products":[],"type":"path_traversal","year":"2026"},"n_packages":4,"n_references":4,"next":{"headline":"rclone: FTP cross-session auth-proxy backend confusion","id":"CVE-2026-88017"},"packages":[{"ecosystem":"Bitnami","fixed":["1.75.1"],"introduced":["0"],"last_affected":[],"package":"rclone","purl":"pkg:bitnami/rclone","source":"BIT-rclone-2026-88016"},{"ecosystem":"Go","fixed":["1.75.1"],"introduced":["0"],"last_affected":[],"package":"github.com/rclone/rclone","purl":null,"source":"GHSA-f8g7-2xjc-7mfh"},{"ecosystem":"Go","fixed":["1.75.1"],"introduced":["0"],"last_affected":[],"package":"github.com/rclone/rclone","purl":"pkg:golang/github.com/rclone/rclone","source":"GHSA-f8g7-2xjc-7mfh"},{"ecosystem":"Go","fixed":["1.75.1"],"introduced":["0"],"last_affected":[],"package":"github.com/rclone/rclone","purl":"pkg:golang/github.com/rclone/rclone","source":"GO-2026-6459"}],"prev":{"headline":"rclone local: crafted Range request against a translated symlink panics (DoS)","id":"CVE-2026-88015"},"products":["rclone"],"published":"2026-09-10","related":[{"cvss_score":9.8,"headline":"rclone serve s3: --auth-proxy without --auth-key authenticates nobody - full SigV4 signature bypass","id":"CVE-2026-88018","kev_date_added":null,"published":"2026-09-10"},{"cvss_score":9.8,"headline":"Rclone: Unauthenticated command execution in `rclone rcd --rc-serve` via inline remote instantiation, bypassing CVE-2026-41179 fix","id":"CVE-2026-49980","kev_date_added":null,"published":"2026-06-24"},{"cvss_score":9.2,"headline":"RClone: Unauthenticated operations/fsinfo allows attacker-controlled backend instantiation and local command execution","id":"CVE-2026-41179","kev_date_added":null,"published":"2026-04-23"},{"cvss_score":9.2,"headline":"Rclone: Unauthenticated options/set allows runtime auth bypass, leading to sensitive operations and command execution","id":"CVE-2026-41176","kev_date_added":null,"published":"2026-04-22"},{"cvss_score":8.8,"headline":"rclone `serve restic --private-repos` authorization bypass: `..` in the URL path lets an authenticated user read, overwrite and delete other users' repositories","id":"CVE-2026-59733","kev_date_added":null,"published":"2026-07-14"},{"cvss_score":8.7,"headline":"Rclone before 1.75.2 Path Traversal via serve webdav MKCOL","id":"CVE-2026-116191","kev_date_added":null,"published":"2026-10-25"},{"cvss_score":8.2,"headline":"rclone from 1.37 before 1.74.2 SSRF via --rc-serve scheme-relative remote roots","id":"CVE-2026-116192","kev_date_added":null,"published":"2026-10-25"}],"sources":[{"class":"attribution","licence":"Apache-2.0","name":"Bitnami","prefix":"BIT"},{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"CC BY 4.0","name":"Go Vulnerability Database","prefix":"GO"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-09-15","vendors":["rclone"]},"summary":"An attacker can use planted symlinks to modify permissions or ownership of files outside the destination directory when using specific rclone flags.","url":"https://insights.sbomify.com/CVE-2026-88016/"}
