{"id":"CVE-2024-11171","summary":"Improper Input Validation in danny-avila/librechat","details":"In danny-avila/librechat version git 0c2a583, there is an improper input validation vulnerability. The application uses multer middleware for handling multipart file uploads. When using in-memory storage (the default setting for multer), there is no limit on the upload file size. This can lead to a server crash due to out-of-memory errors when handling large files. An attacker without any privileges can exploit this vulnerability to cause a complete denial of service. The issue is fixed in version 0.7.6.","modified":"2026-08-12T03:51:18.494753145Z","published":"2025-03-20T10:10:18.684Z","database_specific":{"cna_assigner":"@huntr_ai","cwe_ids":["CWE-770"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/11xxx/CVE-2024-11171.json"},"references":[{"type":"WEB","url":"https://huntr.com/bounties/91717a5a-d653-4e35-b186-9e8d00aa4285"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/11xxx/CVE-2024-11171.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-11171"},{"type":"FIX","url":"https://github.com/danny-avila/librechat/commit/bb58a2d0662ef86dc75a9d2f6560125c018e3836"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/danny-avila/librechat","events":[{"introduced":"0"},{"fixed":"9b118d42de3f99e9c8c85d0beb46d4ae5fd74a4c"},{"fixed":"bb58a2d0662ef86dc75a9d2f6560125c018e3836"}],"database_specific":{"source":["CPE_RANGE","REFERENCES"],"cpe":"cpe:2.3:a:librechat:librechat:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"0"},{"fixed":"0.7.6"}]}}],"versions":["v0.7.6-rc1","v0.7.5","v0.7.5-rc2","v0.7.5-rc1","v0.7.4","v0.7.4-rc1","v0.7.3","v0.7.3-rc2","v0.7.3-rc","v0.7.2","v0.7.1","v0.7.0","v0.6.10","v0.6.9","v0.6.6","v0.6.5","v0.6.1","v0.6.0","v0.5.9","v0.5.8","v0.5.7","v0.5.6","v0.5.5","v0.5.4","v0.5.3","v0.5.2","v0.5.1","v0.5.0","v0.4.8","v0.4.7","v0.4.6","v0.4.5","v0.4.4","v0.4.3","v0.4.2","v0.4.1","v0.4.0","v0.3.3","v0.3.0","v0.2.0","v0.1.1","v0.1.0","v0.0.6","v0.0.3","v0.0.2","v0.0.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2024-11171.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
