Horde · Horde Virtual File System Api · CVE-2026-60102
**Name of the Vulnerable Software and Affected Versions**
Horde Virtual File System (VFS) API versions prior to 3.0.1
**Description**
The Horde Vfs Smb driver contains an OS command injection flaw where the ` escapeShellCommand()` method does not properly sanitize command substitution sequences. Authenticated attackers can exploit this by providing malicious filenames during file upload, folder creation, rename, or deletion operations. These filenames are interpolated into a double-quoted shell context and executed via `proc open()` through `/bin/sh -c` before `smbclient` runs, allowing the execution of arbitrary shell commands on the underlying system.
**Recommendations**
Update Horde Virtual File System (VFS) API to version 3.0.1 or later.
