This vulnerability involves an SQL injection flaw in the 'oid' parameter of the /cancelorder.php component in PHPGurukul Online Shopping Portal Project 2.1. The weakness allows remote attackers to manipulate SQL queries by injecting malicious input, potentially compromising the database integrity or confidentiality. The CVSS 4.0 base score is 5.3, indicating a medium level of severity with network attack vector, low attack complexity, and no user interaction required. No official fix or patch has been published as of the current information.

Successful exploitation of this vulnerability could allow an attacker to execute arbitrary SQL commands on the backend database, potentially leading to unauthorized data access, modification, or deletion. The impact is limited by the low privileges required and the low complexity of the attack, but the overall severity is medium. There is no indication of known active exploitation in the wild at this time.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, it is recommended to implement input validation and parameterized queries for the 'oid' parameter in /cancelorder.php to mitigate SQL injection risks. Monitor vendor channels for updates and apply patches promptly once released.
