Merhaba! Ben Fatih Soysal ve bug\u00fcn Laravel uygulamalar\u0131nda s\u0131k kar\u015f\u0131la\u015f\u0131lan bir g\u00fcvenlik a\u00e7\u0131\u011f\u0131 olan CORS (Cross-Origin Resource Sharing) yanl\u0131\u015f yap\u0131land\u0131rmalar\u0131n\u0131 ele alaca\u011f\u0131z. Bu sorun, \u00f6zellikle farkl\u0131 domain’lerden API \u00e7a\u011fr\u0131lar\u0131 yap\u0131lan uygulamalarda ortaya \u00e7\u0131kar ve ciddi g\u00fcvenlik risklerine yol a\u00e7abilir.<\/p>\n

\u00d6ncelikle, CORS’un ne oldu\u011funu a\u00e7\u0131klayal\u0131m. CORS, bir web taray\u0131c\u0131s\u0131n\u0131n bir domain’den (\u00f6rne\u011fin, sizin Laravel uygulaman\u0131z) ba\u015fka bir domain’e (\u00f6rne\u011fin, bir JavaScript frontend uygulamas\u0131) HTTP istekleri g\u00f6ndermesine izin veren bir g\u00fcvenlik mekanizmas\u0131d\u0131r. Ancak, bu mekanizma do\u011fru \u015fekilde yap\u0131land\u0131r\u0131lmazsa, zararl\u0131 akt\u00f6rlerin izinsiz eri\u015fim elde etmesine olanak tan\u0131r. <\/p>\n

CORS Yanl\u0131\u015f Yap\u0131land\u0131rmalar\u0131n\u0131n Riskleri<\/h2>\n

Yanl\u0131\u015f yap\u0131land\u0131r\u0131lm\u0131\u015f bir CORS mekanizmas\u0131, bir\u00e7ok riske yol a\u00e7abilir. Bunlardan en \u00f6nemlileri \u015funlard\u0131r:<\/p>\n

DoS Sald\u0131r\u0131lar\u0131:<\/strong> Uygulama, a\u015f\u0131r\u0131 istek y\u00fck\u00fcne maruz kalarak hizmet d\u0131\u015f\u0131 b\u0131rak\u0131labilir.<\/li>\n<\/ul>\n
Laravel’de CORS’u Do\u011fru \u015eekilde Yap\u0131land\u0131rma<\/h2>\n
Neyse ki, Laravel’de CORS’u do\u011fru \u015fekilde yap\u0131land\u0131rmak olduk\u00e7a kolayd\u0131r. Bunun i\u00e7in birka\u00e7 y\u00f6ntem mevcuttur. En yayg\u0131n y\u00f6ntem, cors<\/code> middleware’ini kullanmakt\u0131r. Bu middleware’i, app\/Http\/Middleware<\/code> dizinine ekleyerek ve konfig\u00fcrasyonunu yaparak kullanabilirsiniz.<\/p>\n
\nheader('Access-Control-Allow-Origin', '*')\n ->header('Access-Control-Allow-Methods', 'GET, POST, PUT, DELETE')\n ->header('Access-Control-Allow-Headers', 'Content-Type, Authorization');\n }\n}\n<\/code><\/pre>\nBu kod, t\u00fcm origin’lere (Access-Control-Allow-Origin: *<\/code>) GET, POST, PUT ve DELETE metodlar\u0131na izin verir. Ancak, \u00fcretme ortam\u0131nda *<\/code> kullanmaktan ka\u00e7\u0131nman\u0131z ve izin verilen origin’leri belirlemeniz \u00f6nemlidir.<\/strong> G\u00fcvenli\u011finizi art\u0131rmak i\u00e7in, spesifik origin’leri belirtmelisiniz. \u00d6rne\u011fin, sadece https:\/\/fatihsoysal.com<\/code> origin’ine izin vermek isterseniz, Access-Control-Allow-Origin<\/code> header’\u0131n\u0131 buna g\u00f6re de\u011fi\u015ftirmeniz gerekir. Daha detayl\u0131 konfig\u00fcrasyon i\u00e7in Laravel d\u00f6k\u00fcmantasyonuna buradan<\/a> ula\u015fabilirsiniz.<\/p>\n Alternatif Y\u00f6ntemler ve \u0130pu\u00e7lar\u0131<\/h2>\nMiddleware kullanman\u0131n yan\u0131 s\u0131ra, Laravel’de CORS’u yap\u0131land\u0131rman\u0131n ba\u015fka yollar\u0131 da vard\u0131r. \u00d6rne\u011fin, paketler kullanabilir veya kendi middleware’inizi geli\u015ftirebilirsiniz.
