    "summary": "Zendframework Potential Information Disclosure and Insufficient Entropy vulnerability\nIn Zend Framework, Zend_Captcha_Word (v1) and Zend\\Captcha\\Word (v2) generate a \"word\" for a CAPTCHA challenge by selecting a sequence of random letters from a character set. Prior to this advisory, the selection was performed using PHP's internal array_rand() function. This function does not generate sufficient entropy due to its usage of rand() instead of more cryptographically secure methods such as openssl_pseudo_random_bytes(). This could potentially lead to information disclosure should an attacker be able to brute force the random number generation.",
