CVE-2026-2199 identifies a SQL injection vulnerability in the code-projects Online Reviewer System version 1.0. The vulnerability resides in an unspecified function within the /reviewer/system/system/admins/manage/users/user-delete.php file, where the ID parameter is improperly sanitized. This allows an attacker to inject arbitrary SQL commands remotely without requiring authentication or user interaction. The vulnerability can lead to unauthorized access to or modification of the backend database, potentially exposing sensitive user data or enabling destructive actions such as data deletion or corruption. The CVSS 4.0 vector indicates network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), and partial impacts on confidentiality, integrity, and availability (VC:L, VI:L, VA:L). Although no exploits are currently observed in the wild, the public release of exploit code increases the likelihood of exploitation attempts. The lack of available patches or vendor advisories suggests that affected organizations must implement their own mitigations or code fixes. This vulnerability highlights the critical need for input validation and parameterized queries in web applications to prevent injection attacks.

The impact of CVE-2026-2199 on organizations worldwide can be significant. Exploitation allows attackers to execute arbitrary SQL commands on the backend database, potentially leading to unauthorized disclosure of sensitive information such as user credentials, personal data, or internal system details. Attackers could also modify or delete data, undermining data integrity and disrupting normal operations. The availability of the system could be affected if attackers perform destructive queries or cause database crashes. Since the vulnerability requires no authentication and no user interaction, it can be exploited remotely and at scale, increasing the risk of widespread attacks. Organizations relying on the Online Reviewer System for critical review workflows or data management may face operational disruptions, reputational damage, and compliance violations if exploited. The public availability of exploit code further elevates the threat level, as less skilled attackers can attempt exploitation.

To mitigate CVE-2026-2199, organizations should immediately audit and sanitize all inputs to the user-delete.php script, especially the ID parameter. Implementing parameterized queries or prepared statements is essential to prevent SQL injection. If source code access is available, refactor the vulnerable function to use secure coding practices. In the absence of official patches, consider deploying web application firewalls (WAFs) with rules to detect and block SQL injection attempts targeting the affected endpoint. Restrict access to the vulnerable script by IP whitelisting or network segmentation where feasible. Monitor logs for suspicious activity related to the user-delete.php endpoint and the ID parameter. Conduct thorough penetration testing to identify any other injection points. Finally, engage with the vendor or community for updates or patches and plan for timely application once available.
