An attacker who knows a valid chatflow UUID can use that chatflow's stored TTS credential (OpenAI or ElevenLabs API key) to generate unlimited text-to-speech audio. The costs fall on the chatflow owner's account.","solution":"N/A -- no mitigation discussed in source.","labels":["security"],"sourceUrl":"https://github.com/advisories/GHSA-8gj2-2cvc-6xx7","publishedAt":"2026-08-04T19:19:44.000Z","cveId":null,"cweIds":null,"cvssScore":null,"cvssSeverity":"medium","severity":"medium","attackType":["other"],"issueType":"vulnerability","affectedPackages":["flowise@<= 3.1.3 (fixed: 3.1.4)"],"affectedPackageNames":["flowise"],"affectedPackageRefs":["npm:flowise"],"affectedVendors":["OpenAI"],"affectedVendorsRaw":["Flowise","OpenAI TTS","ElevenLabs"],"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-8gj2-2cvc-6xx7"],"affectedPackagesSource":null,"affectedPackagesCheckedAt":null,"patchAvailable":true,"disclosureDate":"2026-08-04T19:19:44.000Z","fixReleasedAt":"2026-07-29T10:15:33.837Z","daysToFix":-6,"fixCheckedAt":"2026-10-29T21:32:10.140Z","capecIds":null,"crossRefCount":0,"attackSophistication":"trivial","impactType":["confidentiality","availability"],"aiComponentTargeted":"api","llmSpecific":false,"classifierConfidence":0.93,"researchCategory":null,"atlasIds":null,"fixes":[{"ecosystem":"npm","name":"flowise","fixedVersion":"3.1.4","matchedVersion":"3.1.4","fixReleasedAt":"2026-07-29T10:15:33.837Z","daysToFix":-6,"match":"ecosystem","source":"tracked","status":"found","checkedAt":"2026-10-29T21:32:09.992Z"}]}}
