{"id":"CVE-2024-11171","state":"PUBLISHED","title":"Improper Input Validation in danny-avila/librechat","description":"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.","publishedAt":"2025-03-20T10:10:18.684Z","updatedAt":"2025-10-15T12:49:28.195Z","severity":{"score":7.5,"label":"High","version":"3.0","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","source":"@huntr_ai"},"assigner":"@huntr_ai","products":["danny-avila danny-avila/librechat"],"affected":[{"vendor":"danny-avila","product":"danny-avila/librechat","versions":[{"version":"unspecified","status":"affected","lessThan":"0.7.6","versionType":"custom"}]}],"references":["https://huntr.com/bounties/91717a5a-d653-4e35-b186-9e8d00aa4285","https://github.com/danny-avila/librechat/commit/bb58a2d0662ef86dc75a9d2f6560125c018e3836"],"weaknesses":["CWE-770"],"ingestedAt":"2026-10-29T20:06:50.777Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2024/11xxx/CVE-2024-11171.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.1","cveMetadata":{"cveId":"CVE-2024-11171","state":"PUBLISHED","datePublished":"2025-03-20T10:10:18.684Z","dateUpdated":"2025-10-15T12:49:28.195Z","assignerShortName":"@huntr_ai","assignerOrgId":"c09c270a-b464-47c1-9133-acb35b22c19a","dateReserved":"2024-11-12T21:34:06.323Z"},"containers":{"cna":{"title":"Improper Input Validation in danny-avila/librechat","descriptions":[{"lang":"en","value":"In danny-avila/librechat version git 0c2a583, there is an improper input validation vulnerability.
