This breaks trust boundaries in the multi-tenant environment (a system serving multiple separate organizations) by letting attackers associate their new accounts with existing organizations they don't own, gaining unauthorized access and escalated privileges.","solution":"N/A -- no mitigation discussed in source.","labels":["security"],"sourceUrl":"https://github.com/advisories/GHSA-48m6-ch88-55mj","publishedAt":"2026-04-16T21:44:24.000Z","cveId":null,"cweIds":null,"cvssScore":null,"cvssSeverity":"high","severity":"high","attackType":["supply_chain"],"issueType":"vulnerability","affectedPackages":["flowise@<= 3.0.13 (fixed: 3.1.0)"],"affectedVendors":["LangChain"],"affectedVendorsRaw":["Flowise"],"classifierModel":"claude-haiku-4-5-20251001","classifierPromptVersion":"v3","cvssVector":null,"attackVector":null,"attackComplexity":null,"privilegesRequired":null,"userInteraction":null,"exploitMaturity":null,"epssScore":null,"patchAvailable":true,"disclosureDate":"2026-04-16T21:44:24.000Z","capecIds":null,"crossRefCount":0,"attackSophistication":"trivial","impactType":["integrity","confidentiality"],"aiComponentTargeted":"api","llmSpecific":false,"classifierConfidence":0.85,"researchCategory":null,"atlasIds":null}}
