An attacker with a stolen session token can send a crafted request that overwrites the credential field, bypassing password verification, hashing enforcement, and policy validation, which gives them permanent access to the account.","solution":"N/A -- no mitigation discussed in source.","labels":["security"],"sourceUrl":"https://github.com/advisories/GHSA-59fh-9f3p-7m39","publishedAt":"2026-05-20T15:44:40.000Z","cveId":null,"cweIds":null,"cvssScore":null,"cvssSeverity":"medium","severity":"medium","attackType":["other"],"issueType":"vulnerability","affectedPackages":["flowise@<= 3.1.1 (fixed: 3.1.2)"],"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":"2026-05-20T15:44:40.000Z","capecIds":null,"crossRefCount":0,"attackSophistication":"moderate","impactType":["integrity","confidentiality"],"aiComponentTargeted":"api","llmSpecific":false,"classifierConfidence":0.85,"researchCategory":null,"atlasIds":null}}
