{"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":"2026-10-02T03:45:20.386131763Z","published":"2025-03-20T10:10:18.684Z","database_specific":{"cwe_ids":["CWE-770"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/11xxx/CVE-2024-11171.json","cna_assigner":"@huntr_ai"},"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/LibreChat-AI/LibreChat","events":[{"introduced":"0"},{"fixed":"bb58a2d0662ef86dc75a9d2f6560125c018e3836"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"0.7.6"}],"source":["AFFECTED_FIELD","REFERENCES"]}}],"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"}]}
