The wrappers pass a caller-controlled target and arguments to `pwsh -Command` or `cmd /c` using a single `ProcessStartInfo.Arguments` string, allowing a double quote in untrusted input to break operating-system-level quoting and cause the shell to execute an additional command with the host process's privileges. The vulnerability is patched in `CliInvoke.Specializations` versions 2.8.5, 2.9.4, 2.10.5, and 3.0.0-beta.1, and in `AlastairLundy.CliInvoke.Specializations` version 2.0.2. No complete workaround is available; users unable to upgrade should reject or remove double quotes from target paths and arguments, additionally reject shell metacharacters in versions 2.2.0 through 2.9.2 and 3.0.0-alpha.1 through 3.0.0-alpha.4, or bypass the PowerShell and Cmd wrappers and invoke target processes directly when handling untrusted input.","state":0,"publishedAt":"2026-09-25T19:53:56.299+00:00","modifiedAt":"2026-09-30T00:06:47.101+00:00","affected":[{"ecosystem":"Vendor product","name":"CliInvoke.Specializations","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"alastairlundy\",\n                    \"product\": \"CliInvoke.Specializations\",\n                    \"versions\": [\n                        {\n                            \"version\": \">= 2.2.0, <= 2.8.4\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 2.9.0, <= 2.9.3\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 2.10.0, <= 2.10.4\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 3.0.0-alpha.1, <= 3.0.0-alpha.4\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 3.0.0-alpha.8, <= 3.0.0-alpha.10\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 1.0.0-rc.1, <= 1.6.1.1\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":8.4,"severity":"HIGH"}],"references":["https://github.com/alastairlundy/CliInvoke/security/advisories/GHSA-wrvw-254r-wpmv"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-100368","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-100368","identifiers":["CVE-2026-100368"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
