CVE-2026-0729 identifies a SQL injection vulnerability in the code-projects Intern Membership Management System version 1.0, specifically in the /intern/admin/add_activity.php file. The vulnerability arises from improper sanitization of the 'Title' parameter, which is susceptible to SQL injection attacks. An attacker can remotely exploit this flaw by sending crafted input to the vulnerable parameter, enabling unauthorized manipulation of backend SQL queries. The CVSS 4.0 vector indicates the attack requires network access (AV:N), low attack complexity (AC:L), no user interaction (UI:N), but requires high privileges (PR:H), and results in low confidentiality, integrity, and availability impacts (VC:L, VI:L, VA:L). The exploit does not require authentication but does require high privileges, which suggests that the attacker must already have some elevated access, possibly through other means. The vulnerability could allow attackers to read, modify, or delete data within the database, potentially leading to data leakage or corruption. Although no known exploits are currently active in the wild, the public availability of exploit code increases the risk of future attacks. The lack of patches or vendor advisories necessitates immediate defensive measures by users of this system.

For European organizations, this vulnerability poses a moderate risk primarily to the confidentiality and integrity of membership data managed by the affected system. Unauthorized SQL injection could lead to exposure of sensitive member information, unauthorized data modification, or denial of service conditions affecting system availability. Organizations in sectors such as education, professional associations, or any entity relying on the Intern Membership Management System for critical operations could face reputational damage, regulatory penalties under GDPR for data breaches, and operational disruptions. The requirement for high privileges to exploit somewhat limits the attack surface but does not eliminate risk, especially if privilege escalation vulnerabilities exist elsewhere. The public availability of exploit code increases the likelihood of opportunistic attacks, making timely mitigation essential.

European organizations should implement specific mitigations including: 1) Immediate code review and remediation of the /intern/admin/add_activity.php file to enforce strict input validation and sanitization on the 'Title' parameter. 2) Refactor database queries to use parameterized statements or prepared queries to prevent SQL injection. 3) Restrict administrative access to the system using network segmentation and multi-factor authentication to reduce the risk of privilege abuse. 4) Monitor database logs and application behavior for anomalous queries indicative of injection attempts. 5) Conduct regular security assessments and penetration testing focused on injection flaws. 6) If possible, upgrade to a patched or newer version of the software once available or consider alternative membership management solutions with stronger security postures. 7) Train administrators on secure coding and operational security best practices to prevent privilege misuse. 8) Implement web application firewalls (WAF) with rules targeting SQL injection patterns as an interim protective measure.
