{"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":"2026-10-28T02:30:39.503384807Z","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/LibreChat-AI/LibreChat","events":[{"introduced":"0"},{"fixed":"9c70d1db969949a5f2f427f447899151e7055638"}],"database_specific":{"extracted_events":[{"strategy":"SplitRange","range":[{"introduced":"0"},{"fixed":"v0.7.9-rc1"}],"source":"AFFECTED_FIELD"},{"source":"REFERENCES_COMMIT","range":[{"fixed":"3af2666890bbf291cb7b9f3e03592d54714f0ff5"}]}]}}],"versions":["0.7.8-NA","0.7.8-rc1","v0.7.8","v0.7.8-rc1","v0.7.7","v0.7.7-rc1","v0.7.6","v0.7.6-rc1","v0.7.5","v0.7.5-rc2","v0.7.5-rc1","v0.7.4","v0.7.4-rc1","v0.7.3","v0.7.3-rc2","v0.7.3-rc","v0.7.2","v0.7.1","v0.7.0","v0.6.10","v0.6.9","v0.6.6","v0.6.5","v0.6.1","v0.6.0","v0.5.9","v0.5.8","v0.5.7","v0.5.6","v0.5.5","v0.5.4","v0.5.3","v0.5.2","v0.5.1","v0.5.0","v0.4.8","v0.4.7","v0.4.6","v0.4.5","v0.4.4","v0.4.3","v0.4.2","v0.4.1","v0.4.0","v0.3.3","v0.3.0","v0.2.0","v0.1.1","v0.1.0","v0.0.6","v0.0.3","v0.0.2","v0.0.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-6088.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:H/PR:L/UI:N/S:U/C:L/I:N/A:L"}]}
