Prior to 1.14.8, the @orpc/server CORS plugin in packages/server/src/plugins/cors.ts copies a client's incoming Vary request header into the response instead of controlling Vary as a response-only header and using Origin for request-origin variation. In deployments behind a shared cache, CDN, or reverse proxy that keys responses using Vary, a client can inject arbitrary variation values, pollute cache keys, and cause inconsistent CORS enforcement for other clients. Default non-cached configurations have no established direct confidentiality, integrity, or availability impact. This issue is fixed in version 1.14.8.","state":0,"publishedAt":"2026-09-16T18:42:45.816+00:00","modifiedAt":"2026-09-16T19:40:51.991+00:00","affected":[{"ecosystem":"Vendor product","name":"orpc","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"middleapi\",\n                    \"product\": \"orpc\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 1.14.8\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:N/SC:L/SI:L/SA:N","score":6.3,"severity":"MEDIUM"}],"references":["https://github.com/middleapi/orpc/security/advisories/GHSA-j9v4-rhgr-4m5f","https://github.com/middleapi/orpc/issues/1661","https://github.com/middleapi/orpc/pull/1662","https://github.com/middleapi/orpc/commit/daabded122a89d323357c4c401e879701864cb2f","https://github.com/middleapi/orpc/releases/tag/v1.14.8"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-77360","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-77360","identifiers":["CVE-2026-77360"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
