CVE-2026-53690 in Redeight
Summary
by MITRE • 06/30/2026
An SQL Injection vulnerability exists in Redeight CMS version 1.0 via the "userEmail" parameter in the POST "/admin/index.php" login endpoint. The application fails to sanitize user input and directly interpolates it into SQL queries without using prepared statements, which allows unauthenticated remote attackers to execute arbitrary SQL commands and extract sensitive database information.

This vulnerability represents a critical sql injection flaw in redeight cms version 1 0 that exploits the useremail parameter within the post request to the admin index php endpoint. the weakness stems from inadequate input validation and sanitization practices where user supplied data flows directly into sql query construction without proper parameterization or escaping mechanisms. attackers can leverage this vulnerability to execute arbitrary sql commands against the underlying database system, potentially gaining unauthorized access to sensitive information including user credentials, personal data, and system configurations.
the technical exploitation occurs at the application layer where the cms fails to implement proper prepared statements or parameterized queries as recommended by owasp and cwe standards. specifically this vulnerability maps to cwe 89 sql injection which is classified as a severe weakness in software applications that process untrusted input through sql commands. the attack vector requires no authentication since the login endpoint accepts useremail parameter without proper validation, making it accessible to any remote attacker who can submit crafted malicious input.
the operational impact of this vulnerability extends beyond simple data theft to include complete database compromise and potential system takeover. successful exploitation allows attackers to extract user credentials, modify or delete database records, and potentially escalate privileges within the application environment. from an att&ck framework perspective this represents a privilege escalation technique through command execution and credential access patterns that can lead to persistent access within the target network infrastructure.
mitigation strategies should focus on implementing proper input validation and sanitization at multiple layers including application code level parameterized queries, web application firewalls, and regular security updates to address known vulnerabilities. developers must adopt secure coding practices that enforce prepared statements for all database interactions and implement proper error handling to prevent information leakage. additionally organizations should conduct regular penetration testing and vulnerability assessments to identify similar injection flaws across their entire application portfolio. the use of automated scanning tools alongside manual code review processes can help detect such issues before they can be exploited by malicious actors, ensuring compliance with industry security standards and reducing overall risk exposure.
