{"id":"CVE-2025-6088","state":"PUBLISHED","title":"Improper Authorization in danny-avila/librechat","description":"In version 0.7.8 of danny-avila/librechat, improper authorization controls in the conversation sharing feature allow unauthorized access to other users' conversations if the conversation ID is known. Although UUIDv4 conversation IDs are generated server-side and are difficult to brute force, they can be obtained from less-protected sources such as server-side access logs, browser history, or screenshots. The vulnerability permits a logged-in user to gain read-only access to another user's conversations by exploiting the `/api/share/conversationID` endpoint, which lacks authorization checks. This issue is resolved in version v0.7.9-rc1.","publishedAt":"2025-09-11T00:43:51.699Z","updatedAt":"2025-09-11T14:42:34.879Z","severity":{"score":4.2,"label":"Medium","version":"3.0","vector":"CVSS:3.0/AV:N/AC:H/PR:L/UI:N/S:U/C:L/I:N/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":"v0.7.9-rc1","versionType":"custom"}]}],"references":["https://huntr.com/bounties/361405bb-a739-41eb-a680-4cb6193e7c76","https://github.com/danny-avila/librechat/commit/3af2666890bbf291cb7b9f3e03592d54714f0ff5"],"weaknesses":["CWE-285"],"ingestedAt":"2026-10-29T20:10:04.440Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2025/6xxx/CVE-2025-6088.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.1","cveMetadata":{"cveId":"CVE-2025-6088","state":"PUBLISHED","datePublished":"2025-09-11T00:43:51.699Z","dateUpdated":"2025-09-11T14:42:34.879Z","assignerShortName":"@huntr_ai","assignerOrgId":"c09c270a-b464-47c1-9133-acb35b22c19a","dateReserved":"2025-06-14T15:10:06.244Z"},"containers":{"cna":{"title":"Improper Authorization in danny-avila/librechat","descriptions":[{"lang":"en","value":"In version 0.7.8 of danny-avila/librechat, improper authorization controls in the conversation sharing feature allow unauthorized access to other users' conversations if the conversation ID is known.
