CVE-2026-24635 is a vulnerability classified as Improper Control of Filename for Include/Require Statement in PHP programs, specifically affecting the EduBlink Core product by DevsBlink. This vulnerability allows Remote File Inclusion (RFI), where an attacker can manipulate the filename parameter used in PHP's include or require statements to load arbitrary files from remote locations. This occurs due to insufficient validation or sanitization of user-supplied input that controls the file path. The affected versions include all releases up to and including version 2.0.7. Exploitation of this vulnerability enables attackers to execute arbitrary PHP code on the server, potentially leading to full system compromise, data theft, or disruption of services. Although no public exploits are currently known, the nature of RFI vulnerabilities makes them highly attractive targets for attackers, especially in web-facing applications. The vulnerability was published on January 23, 2026, and no CVSS score has been assigned yet. The vulnerability is particularly critical because it does not require authentication and can be triggered remotely, increasing the attack surface significantly. EduBlink Core is a PHP-based educational platform, and its compromise could expose sensitive educational data and disrupt critical educational services.

For European organizations, especially those in the education sector using EduBlink Core, this vulnerability poses a significant risk. Successful exploitation can lead to remote code execution, allowing attackers to gain unauthorized access to sensitive student and staff data, alter educational content, or disrupt platform availability. This could result in data breaches, reputational damage, regulatory penalties under GDPR, and operational downtime. Since EduBlink Core is used to manage educational content and user data, the confidentiality, integrity, and availability of critical educational services are at risk. Additionally, compromised systems could be leveraged as pivot points for broader network intrusions within educational institutions or connected organizations. The lack of known exploits currently provides a window for proactive mitigation, but the potential impact remains high due to the ease of exploitation and the critical nature of the affected systems.

1. Immediately monitor for updates or patches from DevsBlink and apply them as soon as they become available. 2. Implement strict input validation and sanitization on all parameters controlling file inclusion to ensure only allowed files and paths are processed. 3. Employ web application firewalls (WAFs) with rules to detect and block suspicious file inclusion attempts. 4. Restrict PHP configuration settings such as 'allow_url_include' to 'Off' to prevent remote file inclusion. 5. Use application-level whitelisting for include/require statements to limit file paths to trusted directories. 6. Conduct thorough code reviews and security testing focusing on file inclusion logic. 7. Isolate vulnerable EduBlink Core instances from critical network segments until patched. 8. Monitor logs for unusual requests or errors related to file inclusion. 9. Educate development and IT teams about secure coding practices related to file handling in PHP. 10. Consider deploying runtime application self-protection (RASP) solutions to detect exploitation attempts in real-time.
