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":"PUBLISHED","assigner":"GitHub_M","published_at":"2026-09-25 20:17:05","updated_at":"2026-09-25 20:17:05"},"problem_types":["CWE-78","CWE-78 CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')"],"metrics":[{"version":"3.1","source":"security-advisories@github.com","type":"Secondary","score":"8.4","severity":"HIGH","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","data":{"version":"3.1","vectorString":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","baseScore":8.4,"baseSeverity":"HIGH","attackVector":"LOCAL","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"HIGH","integrityImpact":"HIGH","availabilityImpact":"HIGH"}},{"version":"3.1","source":"CNA","type":"DECLARED","score":"8.4","severity":"HIGH","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","data":{"attackComplexity":"LOW","attackVector":"LOCAL","availabilityImpact":"HIGH","baseScore":8.4,"baseSeverity":"HIGH","confidentialityImpact":"HIGH","integrityImpact":"HIGH","privilegesRequired":"NONE","scope":"UNCHANGED","userInteraction":"NONE","vectorString":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"}}],"references":[{"url":"https://github.com/alastairlundy/CliInvoke/security/advisories/GHSA-wrvw-254r-wpmv","name":"https://github.com/alastairlundy/CliInvoke/security/advisories/GHSA-wrvw-254r-wpmv","refsource":"security-advisories@github.com","tags":[],"title":"","mime":"","httpstatus":"","archivestatus":"0"},{"url":"https://www.cve.org/CVERecord?id=CVE-2026-100368","name":"CVE Program record","refsource":"CVE.ORG","tags":["canonical"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2026-100368","name":"NVD vulnerability detail","refsource":"NVD","tags":["canonical","analysis"]}],"affected":[{"source":"CNA","vendor":"alastairlundy","product":"CliInvoke.Specializations","version":"affected >= 2.2.0, <= 2.8.4","platforms":[]},{"source":"CNA","vendor":"alastairlundy","product":"CliInvoke.Specializations","version":"affected >= 2.9.0, <= 2.9.3","platforms":[]},{"source":"CNA","vendor":"alastairlundy","product":"CliInvoke.Specializations","version":"affected >= 2.10.0, <= 2.10.4","platforms":[]},{"source":"CNA","vendor":"alastairlundy","product":"CliInvoke.Specializations","version":"affected >= 3.0.0-alpha.1, <= 3.0.0-alpha.4","platforms":[]},{"source":"CNA","vendor":"alastairlundy","product":"CliInvoke.Specializations","version":"affected >= 3.0.0-alpha.8, <= 3.0.0-alpha.10","platforms":[]},{"source":"CNA","vendor":"alastairlundy","product":"CliInvoke.Specializations","version":"affected >= 1.0.0-rc.1, <= 1.6.1.1","platforms":[]}],"timeline":[],"solutions":[],"workarounds":[],"exploits":[],"credits":[],"nvd_cpes":[],"vendor_comments":[],"enrichments":{"kev":null,"epss":null,"legacy_qids":[]},"source_records":{"cve_program":{"containers":{"cna":{"affected":[{"product":"CliInvoke.Specializations","vendor":"alastairlundy","versions":[{"status":"affected","version":">= 2.2.0, <= 2.8.4"},{"status":"affected","version":">= 2.9.0, <= 2.9.3"},{"status":"affected","version":">= 2.10.0, <= 2.10.4"},{"status":"affected","version":">= 3.0.0-alpha.1, <= 3.0.0-alpha.4"},{"status":"affected","version":">= 3.0.0-alpha.8, <= 3.0.0-alpha.10"},{"status":"affected","version":">= 1.0.0-rc.1, <= 1.6.1.1"}]}],"descriptions":[{"lang":"en","value":"CliInvoke is a .NET library for invoking command-line programs, and its `CliInvoke.Specializations` packages provide specialized wrappers for shells such as PowerShell and Windows Command Prompt. `CliInvoke.Specializations` versions 2.2.0 through 2.8.4, 2.9.0 through 2.9.3, 2.10.0 through 2.10.4, 3.0.0-alpha.1 through 3.0.0-alpha.4, and 3.0.0-alpha.8 through 3.0.0-alpha.10, as well as `AlastairLundy.CliInvoke.Specializations` versions 1.0.0-rc.1 through 1.6.1.1, contain an OS command injection vulnerability in their PowerShell and Cmd wrappers.
