Deeper analysis
CVE-2026-2221 is a SQL injection vulnerability in the code-projects Online Reviewer System 1.0, affecting an unknown function within the file /login/index.php of the Login component. The flaw arises from improper neutralization of the Username argument, allowing injection of malicious SQL code. It carries a CVSS v3.1 base score of 7.3 (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L) and is associated with CWE-74 (Improper Neutralization of Special Elements used in an SQL Command) and CWE-89 (SQL Injection). The vulnerability was published on 2026-02-09.
The vulnerability can be exploited remotely by unauthenticated attackers with low complexity and no user interaction required. Successful exploitation enables limited impacts on confidentiality, integrity, and availability, such as extracting sensitive data, modifying database contents, or disrupting service through injected SQL payloads targeting the login functionality.
