# CVE-2026-112344: Syncplify Server! 6.0.0 < 8.8.0 Symbolic Link Jail Escape

Status: published. Published: 2026-10-26. Updated: 2026-11-02.

Syncplify Server! 6.0.0 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.
