An authenticated non-administrative user can build a flow with an MCP Tools component set to a local stdio subprocess transport and run arbitrary operating system commands at the privilege level of the application process. This bypasses the LANGFLOW_CUSTOM_COMPONENT_ADMIN_ONLY and LANGFLOW_BLOCK_CODE_INTERPRETER_COMPONENTS server-side controls. Successful exploitation could expose credentials from the process environment, modify the file system, and reach other services on the server.","solution":"N/A -- no mitigation discussed in source.","labels":["security"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-81941","publishedAt":"2026-09-10T22:17:03.220Z","cveId":"CVE-2026-81941","cweIds":["CWE-284"],"cvssScore":"8.8","cvssSeverity":"high","severity":"high","attackType":["other"],"issueType":"vulnerability","affectedPackages":null,"affectedPackageNames":null,"affectedPackageRefs":null,"affectedVendors":[],"affectedVendorsRaw":["IBM Langflow"],"classifierModel":"claude-haiku-5-5","classifierPromptVersion":"v4","summaryPromptVersion":"v2","headline":"IBM Langflow OSS command execution through MCP Tools stdio transport","headlinePromptVersion":"h1","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","attackVector":"network","attackComplexity":"low","privilegesRequired":"low","userInteraction":"none","exploitMaturity":"unknown","epssScore":0.00626,"epssCheckedAt":"2026-11-04T06:10:13.536Z","kevDateAdded":null,"advisoryAliases":["GHSA-m5q4-pf3r-r78g"],"affectedPackagesSource":null,"affectedPackagesCheckedAt":"2026-11-01T12:08:10.132Z","patchAvailable":null,"disclosureDate":"2026-09-10T22:17:03.220Z","fixReleasedAt":null,"daysToFix":null,"fixCheckedAt":null,"capecIds":null,"crossRefCount":1,"attackSophistication":"moderate","impactType":["confidentiality","integrity","availability"],"aiComponentTargeted":"plugin","llmSpecific":false,"classifierConfidence":0.9,"researchCategory":null,"atlasIds":null,"fixes":[]}}
