Prior to 4.12.25, with credentials: true and no explicit origin (the default wildcard), the CORS Middleware reflects the request's Origin and sends Access-Control-Allow-Credentials: true. Any site can then make credentialed cross-origin requests and read the responses, exposing cookie-authenticated endpoints to arbitrary origins. This vulnerability is fixed in 4.12.25.","state":0,"publishedAt":"2026-06-22T17:15:35.689+00:00","modifiedAt":"2026-06-22T17:26:12.791+00:00","affected":[{"ecosystem":"Vendor product","name":"hono","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"honojs\",\n                    \"product\": \"hono\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 4.12.25\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:L/A:N","score":7.1,"severity":"HIGH"}],"references":["https://github.com/honojs/hono/security/advisories/GHSA-88fw-hqm2-52qc"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-54290","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-54290","identifiers":["CVE-2026-54290"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
