The endpoint compares plaintext username and password from the request body directly against the FLOWISE_USERNAME and FLOWISE_PASSWORD environment variables, with no rate limiting and different responses for success and failure. Attackers can therefore attempt unlimited credential brute-forcing and enumerate valid credentials.","solution":"1) Implement rate limiting on this endpoint, 2) Use constant-time comparison to prevent timing attacks, 3) Consider using hashed comparison, 4) Return generic error messages, 5) Add logging for failed attempts.","labels":["security"],"sourceUrl":"https://github.com/advisories/GHSA-php6-83fg-gw3g","publishedAt":"2026-05-14T14:54:46.000Z","cveId":null,"cweIds":null,"cvssScore":null,"cvssSeverity":"high","severity":"high","attackType":["other"],"issueType":"vulnerability","affectedPackages":["flowise@<= 3.1.1 (fixed: 3.1.2)"],"affectedPackageNames":["flowise"],"affectedPackageRefs":["npm:flowise"],"affectedVendors":[],"affectedVendorsRaw":["FlowiseAI","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-php6-83fg-gw3g"],"affectedPackagesSource":null,"affectedPackagesCheckedAt":null,"patchAvailable":true,"disclosureDate":"2026-05-14T14:54:46.000Z","fixReleasedAt":"2026-04-14T10:52:03.012Z","daysToFix":-30,"fixCheckedAt":"2026-10-29T21:36:24.263Z","capecIds":null,"crossRefCount":0,"attackSophistication":"trivial","impactType":["confidentiality","integrity"],"aiComponentTargeted":"api","llmSpecific":false,"classifierConfidence":0.85,"researchCategory":null,"atlasIds":null,"fixes":[{"ecosystem":"npm","name":"flowise","fixedVersion":"3.1.2","matchedVersion":"3.1.2","fixReleasedAt":"2026-04-14T10:52:03.012Z","daysToFix":-30,"match":"ecosystem","source":"tracked","status":"found","checkedAt":"2026-10-29T21:36:24.117Z"}]}}
