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":"2026-09-16T19:17:38.02+00:00","modifiedAt":"2026-09-30T17:51:56.193+00:00","affected":[],"metrics":[{"system":"CVSS 4.0 · security-advisories@github.com · Secondary","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/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","score":6.3,"severity":"MEDIUM"}],"references":["https://github.com/middleapi/orpc/commit/daabded122a89d323357c4c401e879701864cb2f","https://github.com/middleapi/orpc/issues/1661","https://github.com/middleapi/orpc/pull/1662","https://github.com/middleapi/orpc/releases/tag/v1.14.8","https://github.com/middleapi/orpc/security/advisories/GHSA-j9v4-rhgr-4m5f"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-77360","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Deferred","weaknesses":["CWE-113"],"productCriteria":[],"sourceDates":{"published":"2026-09-16T19:17:38.020","lastModified":"2026-09-30T17:51:56.193"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
