{"id":"CVE-2026-112344","kind":"vulnerability","aliases":["CVE-2026-112344"],"related":[],"title":"Syncplify Server!: symlink escapes user home folder and reads restricted files","description":"Syncplify Server! before 8.8.0 contains a path traversal vulnerability that allows attackers with a symbolic link placed inside a user's home folder to access files outside the virtual filesystem root because confinement is enforced only against the requested path and not the on-disk destination of the link. Attackers can leverage a symlink or, on Windows, a directory junction that points outside the jail to read or access restricted files beyond the intended home-folder boundary.","summary":"Syncplify Server! before 8.8.0 checks file access against the requested path but not where a symbolic link or Windows directory junction actually points. An attacker who can place such a link inside their home folder can read or access files outside that folder.","severity":"high","cvss":7.6,"epss":null,"exploited":false,"exploited_at":null,"products":[],"ecosystems":[],"tags":["file-transfer","package","self-hosted","syncplify","windows"],"not_affected_if":["no-user-created-links","patched-version"],"how_to_check":"- Check the installed Syncplify Server version in the admin console or the install directory; versions below `8.8.0` are affected\n- Look for symbolic links or directory junctions inside user home folders, for example with `dir /AL` on Windows or `find <home> -type l` on Linux\n- unknown","fix":"- Upgrade Syncplify Server to `8.8.0` or later\n- Until upgraded, remove untrusted symbolic links and junctions from user home folders\n- unknown","status":"open","published_at":"2026-10-26T16:17:13+00:00","first_seen_at":"2026-10-26T16:31:01+00:00","triaged_at":"2026-10-26T16:32:52+00:00","updated_at":"2026-10-26T16:32:52+00:00","category":"package","confidence":0.6,"triage":{"at":"2026-10-26T16:32:52Z","model":"claude-haiku-5-5","output":{"fix":"- Upgrade Syncplify Server to `8.8.0` or later\n- Until upgraded, remove untrusted symbolic links and junctions from user home folders\n- unknown","reach":"network","title":"Syncplify Server!: symlink escapes user home folder and reads restricted files","impact":"medium","summary":"Syncplify Server! before 8.8.0 checks file access against the requested path but not where a symbolic link or Windows directory junction actually points.
