Any user holding a valid API key in one workspace can read the full ChatFlow entities of other workspaces, including `flowData`, `chatbotConfig`, and `textToSpeech`/`speechToText` credential IDs. The source notes that most chatflows lack an API key, so the exposure is broad by default.","solution":"N/A -- no mitigation discussed in source.","labels":["security"],"sourceUrl":"https://github.com/advisories/GHSA-c2c9-mfw7-p8hw","publishedAt":"2026-05-20T15:45:19.000Z","cveId":null,"cweIds":null,"cvssScore":null,"cvssSeverity":"medium","severity":"medium","attackType":["data_extraction"],"issueType":"vulnerability","affectedPackages":["flowise@<= 3.1.1 (fixed: 3.1.2)"],"affectedPackageNames":["flowise"],"affectedPackageRefs":["npm:flowise"],"affectedVendors":[],"affectedVendorsRaw":["Flowise"],"classifierModel":"claude-haiku-5-5","classifierPromptVersion":"v4","summaryPromptVersion":"v2","headline":null,"headlinePromptVersion":null,"cvssVector":null,"attackVector":null,"attackComplexity":null,"privilegesRequired":null,"userInteraction":null,"exploitMaturity":null,"epssScore":null,"epssCheckedAt":null,"kevDateAdded":null,"advisoryAliases":["GHSA-c2c9-mfw7-p8hw"],"affectedPackagesSource":null,"affectedPackagesCheckedAt":null,"patchAvailable":true,"disclosureDate":"2026-05-20T15:45:19.000Z","capecIds":null,"crossRefCount":0,"attackSophistication":"trivial","impactType":["confidentiality"],"aiComponentTargeted":"api","llmSpecific":false,"classifierConfidence":0.93,"researchCategory":null,"atlasIds":null}}
