{"cve":"CVE-2026-39411","nvd":{"published":"2026-04-08T20:16:25.560","modified":"2026-07-24T21:10:00.143","status":"Analyzed","description":"LobeHub is a work-and-lifestyle space to find, build, and collaborate with agent teammates that grow with you. Prior to 2.1.48, the webapi authentication layer trusts a client-controlled X-lobe-chat-auth header that is only XOR-obfuscated, not signed or otherwise authenticated. Because the XOR key is hardcoded in the repository, an attacker can forge arbitrary auth payloads and bypass authentication on protected webapi routes. Affected routes include /webapi/chat/[provider], /webapi/models/[provider], /webapi/models/[provider]/pull, and /webapi/create-image/comfyui. This vulnerability is fixed in 2.1.48.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:H/A:N","score":7.1},"cwes":["CWE-287","CWE-290","CWE-345"],"references":["https://github.com/lobehub/lobehub/commit/3327b293d66c013f076cbc16cdbd05a61a3d0428","https://github.com/lobehub/lobehub/pull/13535","https://github.com/lobehub/lobehub/releases/tag/v2.1.48","https://github.com/lobehub/lobehub/security/advisories/GHSA-5mwj-v5jw-5c97","https://github.com/lobehub/lobehub/security/advisories/GHSA-5mwj-v5jw-5c97"],"products":["lobehub:lobehub"],"source":"nvd","synced_at":"2026-10-19T22:28:59.047572785+00:00"},"epss":{"cve":"CVE-2026-39411","score":0.00126,"percentile":0.02244,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-5mwj-v5jw-5c97","url":"https://osv.dev/vulnerability/GHSA-5mwj-v5jw-5c97","summary":"LobeHub: Unauthenticated authentication bypass on `webapi` routes via forgeable `X-lobe-chat-auth` header","modified":"2026-04-09T14:48:25.928787Z","packages":[{"ecosystem":"npm","name":"@lobehub/lobehub","purl":"pkg:npm/%40lobehub/lobehub","ranges":["<2.1.48"],"fixed":["2.1.48"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
