The severity depends on deployment configuration, caching policy, and whether authenticated routes are inadvertently cached.\n\n### Patches\nPatched in `authkit-nextjs` 2.11.1, which applies anti-caching headers to all responses behind authentication.\n\n### Notes\nAuthentication middleware should set anti-caching headers for authenticated routes as a defense in depth measure, but cannot guarantee these headers will not be overwritten elsewhere in the application. We recommend the following:\n  - Review your application code, middleware, and infrastructure configuration to ensure the Cache-Control headers set for authenticated paths prevent inappropriate caching\n  - For application paths that require caching, do not allow user-specific or sensitive authenticated information to be included in the response data or headers","state":0,"publishedAt":"2025-11-20T21:29:16+00:00","modifiedAt":"2025-11-21T15:32:21+00:00","affected":[{"ecosystem":"npm","name":"@workos-inc/authkit-nextjs","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"0"},{"kind":"fixed","version":"2.11.1"}]}],"versions":[],"rawVersionEvidence":null}],"metrics":[{"system":"CVSS_V4","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N/E:U","score":null,"severity":null},{"system":"Publisher rating","vector":null,"score":null,"severity":"HIGH"}],"references":["https://github.com/workos/authkit-nextjs/security/advisories/GHSA-p8pf-44ff-93gf","https://nvd.nist.gov/vuln/detail/CVE-2025-64762","https://github.com/workos/authkit-nextjs/commit/94cf438124993abb0e7c19dac64c3cb5724a15ea","https://github.com/workos/authkit-nextjs","https://github.com/workos/authkit-nextjs/releases/tag/v2.11.1"],"sourceUrl":"https://github.com/advisories/GHSA-p8pf-44ff-93gf","license":"GitHub Advisory Database · CC-BY-4.0","key":"osv:GHSA-p8pf-44ff-93gf","identifiers":["GHSA-p8pf-44ff-93gf","CVE-2025-64762"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
