CVE-2025-13263 is a SQL injection vulnerability identified in SourceCodester Online Magazine Management System version 1.0. The vulnerability resides in the /categories.php file, where the 'c' parameter is improperly sanitized, allowing an attacker to inject malicious SQL code remotely. This injection flaw can be exploited without authentication or user interaction, enabling attackers to manipulate backend database queries. The vulnerability's CVSS 4.0 score is 5.3 (medium severity), reflecting its network attack vector, low attack complexity, and no required privileges or user interaction. The impact on confidentiality, integrity, and availability is limited but present, as attackers may extract or modify data or disrupt service. Although no known exploits are currently active in the wild, a public exploit exists, increasing the risk of future attacks. The vulnerability affects only version 1.0 of the product, and no official patches have been linked yet. The lack of parameterized queries or proper input validation in the affected code is the root cause. This vulnerability is particularly concerning for organizations managing online magazine content, as it could lead to unauthorized data disclosure or content manipulation.

For European organizations using SourceCodester Online Magazine Management System 1.0, this vulnerability poses a risk of unauthorized access to sensitive data stored in the backend database, including potentially user information, content metadata, or configuration data. Attackers could exploit this flaw to extract confidential information, alter published content, or disrupt service availability, impacting business continuity and reputation. Given the remote and unauthenticated nature of the exploit, attackers can target systems over the internet without needing internal access. Media companies, publishers, and content management operations in Europe relying on this system are particularly vulnerable. The medium severity rating indicates a moderate risk, but the availability of a public exploit increases the urgency for mitigation. The impact on data integrity and availability could affect compliance with European data protection regulations such as GDPR if personal data is exposed or altered.

European organizations should immediately audit their use of SourceCodester Online Magazine Management System version 1.0 and identify any instances of the vulnerable /categories.php file. Since no official patch is currently linked, organizations should implement the following mitigations: 1) Apply strict input validation and sanitization on the 'c' parameter to reject malicious SQL payloads. 2) Refactor the code to use parameterized queries or prepared statements to prevent SQL injection. 3) Restrict database user permissions to the minimum necessary to limit the impact of any injection. 4) Employ Web Application Firewalls (WAFs) with rules to detect and block SQL injection attempts targeting the vulnerable parameter. 5) Monitor logs for suspicious query patterns or repeated access to /categories.php with unusual parameters. 6) Consider isolating or disabling the vulnerable functionality if it is not critical. 7) Stay updated with vendor advisories for official patches or updates. 8) Conduct security testing and code reviews to identify and remediate similar injection flaws elsewhere in the application.
