Prior to 1.5.4, the server defaults to CORS_ORIGINS=* combined with allow_credentials=True in lightrag/api/lightrag_server.py, causing Starlette CORSMiddleware to effectively whitelist every origin for credentialed cross-origin requests. Any malicious website visited by an authenticated LightRAG user can silently make authenticated API requests, exfiltrating documents and knowledge graph data or performing destructive actions such as deleting the document store. This vulnerability is fixed in 1.5.4.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:N","score":9.3},"cwes":["CWE-942"],"references":["https://github.com/HKUDS/LightRAG/commit/09567a4c983f580050db63569dd477122c058c3d","https://github.com/HKUDS/LightRAG/commit/df68d75f9dc29dd340ffb6794b48f48c4fdc9a2d","https://github.com/HKUDS/LightRAG/commit/ebba6548639c0f2e8919100eff76b401f1222252","https://github.com/HKUDS/LightRAG/pull/3317","https://github.com/HKUDS/LightRAG/releases/tag/v1.5.4"],"products":[],"source":"nvd","synced_at":"2026-10-25T17:50:08.599881581+00:00"},"epss":{"cve":"CVE-2026-61736","score":0.01422,"percentile":0.72684,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-6x6h-qqr7-855w","url":"https://osv.dev/vulnerability/GHSA-6x6h-qqr7-855w","summary":"LightRAG: CORS Wildcard + Credentials Enables Any-Origin Credentialed Requests","modified":"2026-07-23T15:11:24.272287760Z","packages":[{"ecosystem":"PyPI","name":"lightrag-hku","purl":"pkg:pypi/lightrag-hku","ranges":["<1.5.4"],"fixed":["1.5.4"]}]},{"id":"PYSEC-2026-3474","url":"https://osv.dev/vulnerability/PYSEC-2026-3474","summary":"LightRAG: CORS Wildcard + Credentials Enables Any-Origin Credentialed Requests","modified":"2026-07-23T15:00:12.437223905Z","packages":[{"ecosystem":"PyPI","name":"lightrag-hku","purl":"pkg:pypi/lightrag-hku","ranges":["<1.5.4"],"fixed":["1.5.4"]}]}],"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).
