The application-level size check is also disabled by default, since CONVERSATION_IMPORT_MAX_FILE_SIZE_BYTES is commented out in .env.example. An authenticated user can therefore upload arbitrarily large files, exhausting server disk space and memory.","solution":"Fixed in 0.8.4-rc1.","labels":["security"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-54024","publishedAt":"2026-06-25T17:16:40.153Z","cveId":"CVE-2026-54024","cweIds":["CWE-770"],"cvssScore":"6.5","cvssSeverity":"medium","severity":"medium","attackType":["denial_of_service"],"issueType":"vulnerability","affectedPackages":null,"affectedPackageNames":null,"affectedPackageRefs":null,"affectedVendors":[],"affectedVendorsRaw":["LibreChat"],"classifierModel":"claude-haiku-5-5","classifierPromptVersion":"v4","summaryPromptVersion":"v2","headline":"LibreChat conversation import endpoint accepts unbounded file uploads","headlinePromptVersion":"h1","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","attackVector":"network","attackComplexity":"low","privilegesRequired":"low","userInteraction":"none","exploitMaturity":"unknown","epssScore":0.00444,"epssCheckedAt":"2026-11-09T18:09:51.434Z","kevDateAdded":null,"advisoryAliases":null,"affectedPackagesSource":null,"affectedPackagesCheckedAt":"2026-11-10T00:11:44.945Z","patchAvailable":null,"disclosureDate":"2026-06-25T17:16:40.153Z","fixReleasedAt":null,"daysToFix":null,"fixCheckedAt":null,"capecIds":["CAPEC-130"],"crossRefCount":0,"attackSophistication":"trivial","impactType":["availability"],"aiComponentTargeted":"api","llmSpecific":false,"classifierConfidence":0.85,"researchCategory":null,"atlasIds":null,"fixes":[]}}
