An overly permissive CORS configuration (allow_origins='*' with allow_credentials=True) combined with a refresh token cookie set to SameSite=None lets a malicious webpage call the refresh endpoint with the victim's credentials. The attacker obtains fresh access_token and refresh_token pairs, which grant access to authenticated endpoints, including built-in code-execution functionality, enabling arbitrary code execution and full system compromise.","solution":"N/A -- no mitigation discussed in source.","labels":["security"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2025-34291","publishedAt":"2025-12-06T04:15:47.433Z","cveId":"CVE-2025-34291","cweIds":["CWE-346"],"cvssScore":"8.8","cvssSeverity":"high","severity":"high","attackType":["other"],"issueType":"vulnerability","affectedPackages":["langflow@<= 1.6.9 (fixed: 1.7.0)"],"affectedPackageNames":["langflow"],"affectedPackageRefs":["pypi:langflow"],"affectedVendors":[],"affectedVendorsRaw":["Langflow"],"classifierModel":"claude-haiku-5-5","classifierPromptVersion":"v4","summaryPromptVersion":"v2","headline":"Langflow account takeover and remote code execution via CORS and refresh token","headlinePromptVersion":"h1","cvssVector":null,"attackVector":null,"attackComplexity":null,"privilegesRequired":null,"userInteraction":null,"exploitMaturity":"active","epssScore":0.92808,"epssCheckedAt":"2026-11-04T18:09:14.469Z","kevDateAdded":"2026-05-21","advisoryAliases":["GHSA-577h-p2hh-v4mv"],"affectedPackagesSource":"ghsa","affectedPackagesCheckedAt":"2026-10-10T03:51:47.533Z","patchAvailable":true,"disclosureDate":null,"fixReleasedAt":"2025-12-18T18:17:21.578Z","daysToFix":12,"fixCheckedAt":"2026-10-29T21:42:21.296Z","capecIds":null,"crossRefCount":0,"attackSophistication":"moderate","impactType":["confidentiality","integrity","availability"],"aiComponentTargeted":"plugin","llmSpecific":false,"classifierConfidence":0.9,"researchCategory":null,"atlasIds":null,"fixes":[{"ecosystem":"pypi","name":"langflow","fixedVersion":"1.7.0","matchedVersion":"1.7.0","fixReleasedAt":"2025-12-18T18:17:21.578Z","daysToFix":12,"match":"ecosystem","source":"tracked","status":"found","checkedAt":"2026-10-29T21:42:21.147Z"}]}}
