CVE-2025-11090 is a SQL injection vulnerability identified in itsourcecode Open Source Job Portal version 1.0, specifically in the /admin/employee/index.php?view=edit endpoint. The vulnerability arises from improper sanitization of the 'ID' parameter, which is used in SQL queries without adequate validation or parameterization. This allows remote attackers to inject arbitrary SQL commands by manipulating the ID argument, potentially leading to unauthorized data retrieval, modification, or deletion within the underlying database. The attack vector is network accessible (AV:N), requires low attack complexity (AC:L), and does not require authentication (AT:N) or user interaction (UI:N). The vulnerability impacts the confidentiality, integrity, and availability of the system, but with limited scope confined to the affected product and version. No known exploits are currently active in the wild, but a public exploit exists, increasing the risk of exploitation. The vulnerability was published on September 28, 2025, and carries a CVSS 4.0 base score of 5.3, categorized as medium severity. The lack of patches or vendor advisories at this time necessitates immediate mitigation efforts by users of the affected software.

For European organizations using itsourcecode Open Source Job Portal 1.0, this vulnerability poses a risk of unauthorized access to sensitive employee or job applicant data stored in the portal's database. Exploitation could lead to data breaches, data tampering, or denial of service conditions impacting HR operations. Given the administrative nature of the vulnerable endpoint, attackers could potentially escalate privileges or pivot to other internal systems if the portal is integrated with broader enterprise infrastructure. The exposure is heightened for organizations with publicly accessible administrative interfaces or weak network segmentation. Compliance with GDPR and other data protection regulations means that a breach could result in significant legal and financial repercussions. The medium severity rating suggests a moderate but tangible risk that requires timely remediation to prevent exploitation.

1. Immediately restrict access to the /admin/employee/index.php endpoint using network controls such as VPNs, IP whitelisting, or firewall rules to limit exposure to trusted administrators only. 2. Implement input validation and sanitization on the 'ID' parameter to reject or properly encode malicious input. 3. Refactor the backend code to use parameterized queries or prepared statements to prevent SQL injection. 4. Monitor logs for suspicious activity targeting the vulnerable endpoint, including unusual query parameters or repeated access attempts. 5. If possible, upgrade to a patched version once available or apply community-provided patches after thorough testing. 6. Conduct security audits and penetration testing focused on web application vulnerabilities in the job portal and related systems. 7. Educate administrators on secure usage practices and the risks of exposing administrative interfaces publicly. 8. Implement web application firewalls (WAF) with rules to detect and block SQL injection attempts targeting this endpoint.
