{"id":"CVE-2025-47275","state":"PUBLISHED","title":"Brute Force Authentication Tags of CookieStore Sessions in Auth0-PHP SDK","description":"Auth0-PHP provides the PHP SDK for Auth0 Authentication and Management APIs. Starting in version 8.0.0-BETA1 and prior to version 8.14.0, session cookies of applications using the Auth0-PHP SDK configured with CookieStore have authentication tags that can be brute forced, which may result in unauthorized access. Certain pre-conditions are required to be vulnerable to this issue: Applications using the Auth0-PHP SDK, or the Auth0/symfony, Auth0/laravel-auth0, and Auth0/wordpress SDKs that rely on the Auth0-PHP SDK; and session storage configured with CookieStore. Upgrade Auth0/Auth0-PHP to v8.14.0 to receive a patch. As an additional precautionary measure, rotating cookie encryption keys is recommended. Note that once updated, any previous session cookies will be rejected.","publishedAt":"2025-05-15T21:13:01.150Z","updatedAt":"2025-05-22T20:03:34.201Z","severity":{"score":9.1,"label":"Critical","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["auth0 auth0-PHP"],"affected":[{"vendor":"auth0","product":"auth0-PHP","versions":[{"version":">= 8.0.0-BETA1, < 8.14.0","status":"affected"}]}],"references":["https://github.com/auth0/auth0-PHP/security/advisories/GHSA-g98g-r7gf-2r25","https://github.com/auth0/laravel-auth0/security/advisories/GHSA-9fwj-9mjf-rhj3","https://github.com/auth0/symfony/security/advisories/GHSA-9wg9-93h9-j8ch","https://github.com/auth0/wordpress/security/advisories/GHSA-2f4r-34m4-3w8q","https://github.com/auth0/auth0-PHP/commit/52a79480fdb246f59dbc089b81a784ae049bd389","https://github.com/auth0/auth0-PHP/releases/tag/8.14.0"],"weaknesses":["CWE-287"],"ingestedAt":"2026-10-29T20:09:23.771Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2025/47xxx/CVE-2025-47275.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.1","cveMetadata":{"cveId":"CVE-2025-47275","state":"PUBLISHED","datePublished":"2025-05-15T21:13:01.150Z","dateUpdated":"2025-05-22T20:03:34.201Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2025-05-05T16:53:10.372Z"},"containers":{"cna":{"title":"Brute Force Authentication Tags of CookieStore Sessions in Auth0-PHP SDK","descriptions":[{"lang":"en","value":"Auth0-PHP provides the PHP SDK for Auth0 Authentication and Management APIs.
