{"id":"CVE-2025-8849","state":"PUBLISHED","title":"Denial of Service in danny-avila/librechat","description":"LibreChat version 0.7.9 is vulnerable to a Denial of Service (DoS) attack due to unbounded parameter values in the `/api/memories` endpoint. The `key` and `value` parameters accept arbitrarily large inputs without proper validation, leading to a null pointer error in the Rust-based backend when excessively large values are submitted. This results in the inability to create new memories, impacting the stability of the service.","publishedAt":"2025-10-30T23:42:41.552Z","updatedAt":"2025-10-31T15:09:34.057Z","severity":{"score":5.4,"label":"Medium","version":"3.0","vector":"CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:L","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":"v0.8.0-rc2","versionType":"custom"}]}],"references":["https://huntr.com/bounties/e9d9404c-cd19-4226-a580-9cba14b7d7d6","https://github.com/danny-avila/librechat/commit/edf33bedcbb08c33e59df76f06454ed7efd896f9"],"weaknesses":["CWE-400"],"ingestedAt":"2026-10-29T20:10:04.440Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2025/8xxx/CVE-2025-8849.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2025-8849","state":"PUBLISHED","datePublished":"2025-10-30T23:42:41.552Z","dateUpdated":"2025-10-31T15:09:34.057Z","assignerShortName":"@huntr_ai","assignerOrgId":"c09c270a-b464-47c1-9133-acb35b22c19a","dateReserved":"2025-08-10T18:16:35.321Z"},"containers":{"cna":{"title":"Denial of Service in danny-avila/librechat","descriptions":[{"lang":"en","value":"LibreChat version 0.7.9 is vulnerable to a Denial of Service (DoS) attack due to unbounded parameter values in the `/api/memories` endpoint.
