This vulnerability, identified as CVE-2026-5634, resides in the \u003ccode\u003e/book_car.php\u003c/code\u003e file, specifically within the parameter handler. An attacker can remotely manipulate the \u003ccode\u003efname\u003c/code\u003e argument to inject arbitrary SQL commands. Given the availability of exploit code, the risk of exploitation is elevated. Successful exploitation could lead to unauthorized data access, modification, or deletion, potentially compromising the entire application and its data. Defenders need to focus on detecting and preventing malicious requests targeting the vulnerable endpoint.\u003c/p\u003e\n\u003ch2 id=\"attack-chain\"\u003eAttack Chain\u003c/h2\u003e\n\u003col\u003e\n\u003cli\u003eAn unauthenticated attacker identifies the vulnerable \u003ccode\u003e/book_car.php\u003c/code\u003e endpoint.\u003c/li\u003e\n\u003cli\u003eThe attacker crafts a malicious HTTP GET or POST request to \u003ccode\u003e/book_car.php\u003c/code\u003e, injecting SQL code into the \u003ccode\u003efname\u003c/code\u003e parameter.
