Prior to 0.8.4-rc1, the fix for CVE-2024-11171 (commit bb58a2d0) added limits: { fileSize } to createMulterInstance() in the file upload routes. However, the POST /api/convos/import endpoint uses a separate multer instance that was never updated with the same limits configuration. Combined with the application-level size check being disabled by default (the CONVERSATION_IMPORT_MAX_FILE_SIZE_BYTES env var is commented out in .env.example), an authenticated user can upload arbitrarily large files to exhaust server disk space and memory. This vulnerability is fixed in 0.8.4-rc1."}], "source": {"advisory": "GHSA-52f6-fqwv-jccf", "discovery": "UNKNOWN"}}, "adp": [{"references": [{"url": "https://github.com/danny-avila/LibreChat/security/advisories/GHSA-52f6-fqwv-jccf", "tags": ["exploit"]}], "metrics": [{"other": {"type": "ssvc", "content": {"timestamp": "2026-06-25T17:53:03.064873Z", "id": "CVE-2026-54024", "options": [{"Exploitation": "poc"}, {"Automatable": "no"}, {"Technical Impact": "partial"}], "role": "CISA Coordinator", "version": "2.0.3"}}}], "title": "CISA ADP Vulnrichment", "providerMetadata": {"orgId": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "shortName": "CISA-ADP", "dateUpdated": "2026-06-25T17:55:53.764Z"}}]}}
