The problem was that UploadedFile references (pointers to files stored in cloud services like AWS S3 or Google Cloud Storage) were not checked before being sent to the server, allowing attackers to trick the server into reading files using its own permissions rather than the attacker's limited access.","solution":"This issue has been fixed in versions 1.106.0 and 2.0.0b6. Update to one of these versions or later.","labels":["security"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-54249","publishedAt":"2026-07-29T21:17:47.323Z","cveId":"CVE-2026-54249","cweIds":["CWE-918"],"cvssScore":"6.8","cvssSeverity":"medium","severity":"medium","attackType":["data_extraction"],"issueType":"vulnerability","affectedPackages":null,"affectedVendors":["LangChain"],"affectedVendorsRaw":["Pydantic AI","Vercel AI adapter"],"classifierModel":"claude-haiku-4-5-20251001","classifierPromptVersion":"v3","cvssVector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:H/I:N/A:N","attackVector":"network","attackComplexity":"high","privilegesRequired":"none","userInteraction":"none","exploitMaturity":"unknown","epssScore":0,"patchAvailable":null,"disclosureDate":"2026-07-29T21:17:47.323Z","capecIds":["CAPEC-664"],"crossRefCount":0,"attackSophistication":"moderate","impactType":["confidentiality"],"aiComponentTargeted":"api","llmSpecific":false,"classifierConfidence":0.92,"researchCategory":null,"atlasIds":null}}
