After installation, the server immediately imports the package using dynamic import (a technique where code loads modules at runtime), executing arbitrary attacker code with full server privileges (RCE - remote code execution).","solution":"N/A -- no mitigation discussed in source.","labels":["security"],"sourceUrl":"https://github.com/advisories/GHSA-wcjj-9m6g-2fr2","publishedAt":"2026-09-09T23:49:20.000Z","cveId":"CVE-2026-59176","cweIds":null,"cvssScore":null,"cvssSeverity":"high","severity":"high","attackType":["supply_chain"],"issueType":"vulnerability","affectedPackages":["functype-mcp-server@<= 1.4.3 (fixed: 1.4.4)"],"affectedVendors":["LangChain"],"affectedVendorsRaw":["functype-mcp-server","functype"],"classifierModel":"claude-haiku-4-5-20251001","classifierPromptVersion":"v3","cvssVector":null,"attackVector":null,"attackComplexity":null,"privilegesRequired":null,"userInteraction":null,"exploitMaturity":"unknown","epssScore":0,"patchAvailable":true,"disclosureDate":"2026-09-09T23:49:20.000Z","capecIds":null,"crossRefCount":0,"attackSophistication":"moderate","impactType":["confidentiality","integrity","availability"],"aiComponentTargeted":"agent","llmSpecific":false,"classifierConfidence":0.85,"researchCategory":null,"atlasIds":["AML.T0010"]}}
