Validation checks only node_template[\"code\"][\"value\"], not the dynamic CodeInput fields that store generated ToolGuard Python files, so malicious Python persisted in Flow.data runs server-side when a guarded tool is invoked. Authenticated users with flow creation privileges can gain arbitrary Python execution, and the agentic MCP update_flow_component_field tool, which accepts attacker-controlled user_id parameters, enables cross-tenant injection into other users' flows.","solution":"N/A -- no mitigation discussed in source.","labels":["security"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-9135","publishedAt":"2026-07-17T19:17:19.390Z","cveId":"CVE-2026-9135","cweIds":["CWE-94"],"cvssScore":"9.9","cvssSeverity":"critical","severity":"critical","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 code injection in Policies ToolGuard integration","headlinePromptVersion":"h1","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","attackVector":"network","attackComplexity":"low","privilegesRequired":"low","userInteraction":"none","exploitMaturity":"unknown","epssScore":0.00841,"epssCheckedAt":"2026-11-12T06:11:40.433Z","kevDateAdded":null,"advisoryAliases":["GHSA-mmph-9cw2-f8r6"],"affectedPackagesSource":null,"affectedPackagesCheckedAt":"2026-11-09T18:10:04.321Z","patchAvailable":null,"disclosureDate":"2026-07-17T19:17:19.390Z","fixReleasedAt":null,"daysToFix":null,"fixCheckedAt":null,"capecIds":["CAPEC-242"],"crossRefCount":0,"attackSophistication":"moderate","impactType":["confidentiality","integrity"],"aiComponentTargeted":"plugin","llmSpecific":false,"classifierConfidence":0.9,"researchCategory":null,"atlasIds":null,"fixes":[]}}
