{"id":"CVE-2025-6088","summary":"Improper Authorization in danny-avila/librechat","details":"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.","modified":"2026-08-12T03:51:39.314420461Z","published":"2025-09-11T00:43:51.699Z","database_specific":{"cna_assigner":"@huntr_ai","cwe_ids":["CWE-285"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/6xxx/CVE-2025-6088.json"},"references":[{"type":"WEB","url":"https://huntr.com/bounties/361405bb-a739-41eb-a680-4cb6193e7c76"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/6xxx/CVE-2025-6088.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-6088"},{"type":"FIX","url":"https://github.com/danny-avila/librechat/commit/3af2666890bbf291cb7b9f3e03592d54714f0ff5"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/danny-avila/librechat","events":[{"introduced":"f7777a2723e8e51f3ff464d4e672db46905964a5"},{"fixed":"3af2666890bbf291cb7b9f3e03592d54714f0ff5"}],"database_specific":{"extracted_events":[{"introduced":"0.7.8-NA"},{"last_affected":"0.7.8-NA"},{"introduced":"0.7.8-rc1"},{"last_affected":"0.7.8-rc1"}],"source":["CPE_STRING","REFERENCES"],"cpe":["cpe:2.3:a:librechat:librechat:0.7.8:-:*:*:*:*:*:*","cpe:2.3:a:librechat:librechat:0.7.8:rc1:*:*:*:*:*:*"]}}],"versions":["0.7.8-NA","0.7.8-rc1","v0.7.8"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-6088.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:H/PR:L/UI:N/S:U/C:L/I:N/A:L"}]}
