CVE-2026-4625 is a SQL injection vulnerability identified in SourceCodester Online Admission System version 1.0. The vulnerability resides in an unspecified function within the /programmes.php file, where the 'program' parameter is improperly sanitized, allowing an attacker to inject malicious SQL code. This injection flaw can be exploited remotely without any authentication or user interaction, making it highly accessible to attackers. The vulnerability has a CVSS 4.0 base score of 6.9, categorized as medium severity, reflecting its potential to compromise the confidentiality, integrity, and availability of the backend database. Exploiting this vulnerability could allow attackers to retrieve sensitive student admission data, modify records, or disrupt the admission process. Although no active exploitation has been reported, the public availability of exploit code increases the likelihood of attacks. The absence of official patches or mitigations from the vendor necessitates immediate defensive measures by users of the affected software. Given the critical nature of admission systems in educational institutions, this vulnerability poses a significant risk to data privacy and operational continuity.

The exploitation of CVE-2026-4625 could have several adverse impacts on organizations using the SourceCodester Online Admission System. Attackers could gain unauthorized access to sensitive student and applicant data, leading to privacy violations and potential regulatory non-compliance. Data integrity could be compromised by unauthorized modification or deletion of admission records, potentially disrupting enrollment processes and causing administrative chaos. Availability of the admission system could also be affected if attackers execute destructive SQL commands or cause database corruption. The remote and unauthenticated nature of the exploit increases the attack surface, making it easier for threat actors to target vulnerable systems. Educational institutions, especially those relying heavily on this software for admissions, may face reputational damage, legal consequences, and operational downtime. The public disclosure of exploit code further elevates the risk of widespread attacks, particularly from opportunistic attackers and script kiddies.

To mitigate CVE-2026-4625, organizations should first verify if they are running SourceCodester Online Admission System version 1.0 and specifically assess the /programmes.php file for the vulnerable 'program' parameter. Immediate steps include implementing input validation and parameterized queries or prepared statements to prevent SQL injection. If vendor patches become available, apply them promptly. In the absence of official patches, consider deploying Web Application Firewalls (WAFs) with custom rules to detect and block malicious SQL injection payloads targeting the 'program' parameter. Conduct regular security audits and code reviews focusing on input sanitization practices. Restrict database user privileges to the minimum necessary to limit the impact of a potential injection. Monitor logs for unusual database queries or errors indicative of injection attempts. Educate development teams on secure coding practices to prevent similar vulnerabilities in future releases. Finally, maintain regular backups of admission data to enable recovery in case of data corruption or loss.
