{"id":"UBUNTU-CVE-2026-60102","details":"Horde Virtual File System (VFS) API before 3.0.1 contains an OS command injection vulnerability in the Horde_Vfs_Smb driver where the _escapeShellCommand() method fails to sanitize command substitution sequences, allowing authenticated attackers to inject arbitrary shell commands through user-controlled filenames. Attackers can supply malicious filenames containing unescaped command substitution payloads through operations such as file upload, folder creation, rename, or deletion, which are interpolated into a double-quoted shell context and executed via proc_open() through /bin/sh -c before smbclient runs, resulting in arbitrary command execution on the underlying system.","modified":"2026-07-15T19:45:32.842763296Z","published":"2026-07-08T17:17:00Z","upstream":["CVE-2026-60102"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-60102"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-60102"},{"type":"REPORT","url":"https://github.com/horde/Vfs/pull/10"},{"type":"REPORT","url":"https://github.com/horde/Vfs/commit/41f74b4acfc144e09013d04dd121e0a5da808361"}],"affected":[{"package":{"name":"php-horde-vfs","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/php-horde-vfs?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.3.0-1","2.3.0-2","2.3.1-1","2.3.1-1ubuntu1"],"ecosystem_specific":{"binaries":[{"binary_name":"php-horde-vfs","binary_version":"2.3.1-1ubuntu1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-60102.json"}},{"package":{"name":"php-horde-vfs","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/php-horde-vfs?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.4.0-1","2.4.0-1ubuntu1"],"ecosystem_specific":{"binaries":[{"binary_name":"php-horde-vfs","binary_version":"2.4.0-1ubuntu1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-60102.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N"},{"type":"Ubuntu","score":"medium"}]}
