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.","evidence":"cve:CVE-2026-100368","products":[{"name":{"value":"CliInvoke.Specializations","evidence":"/containers/cna/affected/0/product"},"prerequisites":[],"fixed_versions":[],"affected_versions":[]}],"severity":"high","structured":{"id":"CVE-2026-100368","aliases":["CVE-2026-100368"],"metrics":[{"cvssV3_1":{"scope":"UNCHANGED","version":"3.1","baseScore":8.4,"attackVector":"LOCAL","baseSeverity":"HIGH","vectorString":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","integrityImpact":"HIGH","userInteraction":"NONE","attackComplexity":"LOW","availabilityImpact":"HIGH","privilegesRequired":"NONE","confidentialityImpact":"HIGH"}}],"affected":[{"vendor":"alastairlundy","product":"CliInvoke.Specializations","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"}]}],"modified":"2026-09-30T00:06:47.101Z","provider":"cve","references":["https://github.com/alastairlundy/CliInvoke/security/advisories/GHSA-wrvw-254r-wpmv"],"provider_metadata":{"adp":[{"title":"CISA ADP Vulnrichment","metrics":[{"other":{"type":"ssvc","content":{"id":"CVE-2026-100368","role":"CISA Coordinator","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"total"}],"version":"2.0.3","timestamp":"2026-09-30T00:06:37.206021Z"}}}],"providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-09-30T00:06:47.101Z"}}],"cna":{"orgId":"a0819718-46f1-4df5-94e2-005712e83aaa","shortName":"GitHub_M","dateUpdated":"2026-09-25T19:53:56.299Z"}}},"related_cves":[{"value":"CVE-2026-100368","evidence":"/cveMetadata/cveId"}],"security_relevant":true,"severity_evidence":"/containers/cna/metrics"}}],"next_after":4072,"next_before":4072}
