{"id":"CVE-2025-48947","aliases":["GHSA-f3fg-mf2q-fj3f"],"url":"https://o3.security/vulnerability/CVE-2025-48947","summary":"NextJS-Auth0 SDK Vulnerable to CDN Caching of Session Cookies","details":"The Auth0 Next.js SDK is a library for implementing user authentication in Next.js applications. In Auth0 Next.js SDK versions 4.0.1 through 4.6.0, `__session` cookies set by auth0.middleware may be cached by CDNs due to missing Cache-Control headers. Three preconditions must be met in order for someone to be affected by the vulnerability: Applications using the NextJS-Auth0 SDK, versions between 4.0.1 to 4.6.0, applications using CDN or edge caching that caches responses with the Set-Cookie header, and if the Cache-Control header is not properly set for sensitive responses. Users should upgrade auth0/nextjs-auth0 to v4.6.1 to receive a patch.","published":"2025-06-04T20:14:44.369Z","modified":"2026-08-12T03:51:35.180443714Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"@auth0/nextjs-auth0","fixedVersion":"4.6.1"}],"fix":{"url":"https://github.com/auth0/nextjs-auth0/commit/12a62ca596db3b0827b39a4b865b882423e7cb1e","label":"auth0/nextjs-auth0@12a62ca"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/48xxx/CVE-2025-48947.json"},{"type":"ADVISORY","url":"https://github.com/auth0/nextjs-auth0/security/advisories/GHSA-f3fg-mf2q-fj3f"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-48947"},{"type":"WEB","url":"https://github.com/auth0/nextjs-auth0/commit/12a62ca596db3b0827b39a4b865b882423e7cb1e"},{"type":"PACKAGE","url":"https://github.com/auth0/nextjs-auth0"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:35.180443714Z"}}
