{"cve":"CVE-2025-48947","nvd":{"published":"2025-06-04T21:15:40.420","modified":"2026-06-17T09:30:32.030","status":"Deferred","description":"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.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:P/VC:H/VI:H/VA:H/SC:L/SI:L/SA:L","score":7.7},"cvss_v3":null,"cwes":["CWE-525"],"references":["https://github.com/auth0/nextjs-auth0/security/advisories/GHSA-f3fg-mf2q-fj3f"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:02:23.998251710+00:00"},"epss":{"cve":"CVE-2025-48947","score":0.00435,"percentile":0.37853,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-f3fg-mf2q-fj3f","url":"https://osv.dev/vulnerability/GHSA-f3fg-mf2q-fj3f","summary":"NextJS-Auth0 SDK Vulnerable to CDN Caching of Session Cookies","modified":"2025-06-04T22:57:21Z","packages":[{"ecosystem":"npm","name":"@auth0/nextjs-auth0","purl":"pkg:npm/%40auth0/nextjs-auth0","ranges":[">=4.0.1 <4.6.1"],"fixed":["4.6.1"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
