The `createLead` function in `/packages/server/src/services/leads/index.ts` calls `Object.assign(newLead, body)` without filtering fields, overwriting the auto-generated values before save. The endpoint is listed in `WHITELIST_URLS` in `/packages/server/src/utils/constants.ts`, so no authentication is required. The source is tagged CWE-915.","solution":"N/A -- no mitigation discussed in source.","labels":["security"],"sourceUrl":"https://github.com/advisories/GHSA-mq4r-h2gh-qv7x","publishedAt":"2026-03-06T22:19:14.000Z","cveId":"CVE-2026-30822","cweIds":null,"cvssScore":null,"cvssSeverity":"high","severity":"high","attackType":["other"],"issueType":"vulnerability","affectedPackages":["flowise@<= 3.0.12 (fixed: 3.0.13)"],"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":"unknown","epssScore":0.14974,"epssCheckedAt":"2026-11-04T06:10:13.536Z","kevDateAdded":null,"advisoryAliases":["GHSA-mq4r-h2gh-qv7x"],"affectedPackagesSource":null,"affectedPackagesCheckedAt":null,"patchAvailable":null,"disclosureDate":null,"fixReleasedAt":"2026-02-03T14:06:55.481Z","daysToFix":-31,"fixCheckedAt":"2026-10-29T21:40:06.908Z","capecIds":null,"crossRefCount":0,"attackSophistication":"trivial","impactType":["integrity"],"aiComponentTargeted":"api","llmSpecific":false,"classifierConfidence":0.9,"researchCategory":null,"atlasIds":null,"fixes":[{"ecosystem":"npm","name":"flowise","fixedVersion":"3.0.13","matchedVersion":"3.0.13","fixReleasedAt":"2026-02-03T14:06:55.481Z","daysToFix":-31,"match":"ecosystem","source":"tracked","status":"found","checkedAt":"2026-10-29T21:40:06.762Z"}]}}
