This vulnerability, assigned CVE-2026-5814, resides within the \u003ccode\u003e/admin/check_availability.php\u003c/code\u003e file. An attacker can remotely exploit this vulnerability by injecting malicious SQL code into the \u003ccode\u003eregno\u003c/code\u003e parameter. The vulnerability was publicly disclosed and an exploit is available, increasing the risk of active exploitation. Successful exploitation allows attackers to potentially read, modify, or delete sensitive data within the application's database, leading to data breaches, account compromise, and complete system takeover. Organizations using the affected version of PHPGurukul Online Course Registration should take immediate action to mitigate this risk.\u003c/p\u003e\n\u003ch2 id=\"attack-chain\"\u003eAttack Chain\u003c/h2\u003e\n\u003col\u003e\n\u003cli\u003eAn attacker identifies a vulnerable PHPGurukul Online Course Registration 3.1 instance accessible over the internet.\u003c/li\u003e\n\u003cli\u003eThe attacker crafts a malicious HTTP request targeting the \u003ccode\u003e/admin/check_availability.php\u003c/code\u003e file.\u003c/li\u003e\n\u003cli\u003eThe attacker injects SQL code into the \u003ccode\u003eregno\u003c/code\u003e parameter within the HTTP GET or POST request.
