| + | # CVE-2026-81830 - Windows openvpnserv config path validation bypass via sibling directories |
| + | |
| + | OpenVPN 2.x on Windows allows local users to start openvpn.exe with a config file outside the administratively allowed config directories, because `CheckConfigPath()` in `openvpnserv` did not detect and refuse sibling directories of an allowed path. |
| + | |
| + | OpenVPN version 2.4.0 through 2.6.22 are affected. This is fixed in version 2.6.23 <2.7.x FIXED VERSION TBD>. |
