CVE-2026-3135 identifies a SQL Injection vulnerability in the itsourcecode News Portal Project version 1.0, specifically within the /admin/add-category.php file. The vulnerability stems from improper sanitization or validation of the 'Category' parameter, which is susceptible to malicious SQL code injection. This flaw allows an unauthenticated remote attacker to manipulate SQL queries executed by the backend database, potentially leading to unauthorized data disclosure, data modification, or disruption of service. The vulnerability does not require user interaction or privileges, making it easier to exploit remotely. The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:P) reflects network attack vector, low attack complexity, no privileges or user interaction needed, and partial impacts on confidentiality, integrity, and availability. Although no active exploits have been reported in the wild, public exploit code availability increases the risk of attacks. The lack of patches or official fixes necessitates immediate attention to secure the affected component. SQL Injection remains a critical web application security issue due to its potential to compromise backend databases and overall system security.

The impact of this SQL Injection vulnerability is significant for organizations using the itsourcecode News Portal Project 1.0. Successful exploitation can lead to unauthorized access to sensitive data stored in the backend database, including user credentials, content management data, or administrative information. Attackers could alter or delete data, undermining data integrity and potentially causing service disruption or denial of service. The vulnerability’s remote and unauthenticated nature increases the attack surface, allowing attackers to exploit it without needing legitimate credentials or user interaction. This can lead to data breaches, reputational damage, and regulatory compliance issues, especially for organizations handling personal or sensitive information. Additionally, attackers could leverage this vulnerability as a foothold for further network intrusion or lateral movement within the affected environment. The medium severity rating reflects partial but meaningful impacts on confidentiality, integrity, and availability, which can have serious operational and business consequences.

To mitigate CVE-2026-3135, organizations should immediately conduct a thorough code review of the /admin/add-category.php file, focusing on the handling of the 'Category' parameter. Implement parameterized queries or prepared statements to prevent SQL Injection by separating SQL code from data inputs. Apply strict input validation and sanitization to ensure only expected data formats are accepted. Restrict access to the administrative interface to trusted IP addresses or via VPN to reduce exposure. Monitor web application logs for suspicious query patterns indicative of injection attempts. If possible, deploy a Web Application Firewall (WAF) with rules to detect and block SQL Injection payloads targeting this endpoint. Since no official patch is currently available, consider isolating or disabling the vulnerable functionality until a fix is released. Educate developers on secure coding practices to prevent similar vulnerabilities in future releases. Finally, maintain regular backups of databases and critical data to enable recovery in case of compromise.
