Executive Summary

CVE-2026-30760 is a high-severity security vulnerability in SourceBans Material Admin versions before 1.1.6. It involves an authenticated SQL injection in the ChangeAdminsInfos endpoint, where user input fields like VK or Skype/Discord profile links are improperly sanitized and directly used in SQL UPDATE queries. This flaw is compounded by missing CSRF protections, allowing attackers to perform a one-click account takeover by chaining a CSRF attack with the SQL injection. Exploiting this vulnerability enables attackers to manipulate arbitrary user data within the web application.

Further exploitation can lead to privilege escalation, full administrator account takeover, and potentially remote code execution on the host system by leveraging additional vulnerabilities such as stored cross-site scripting or weak file upload validation.

Impact Analysis

This vulnerability can have severe impacts including unauthorized manipulation of user data, privilege escalation to the highest administrative level, and full account takeover of administrator accounts.

Attackers can also achieve remote code execution on the server hosting the application, which could lead to complete compromise of the system, data breaches, and disruption of services.

The exploitation requires only a crafted request and can be triggered via CSRF, making it easier for attackers to exploit without direct authentication.

Detection Guidance

This vulnerability involves an authenticated SQL injection in the ChangeAdminsInfos endpoint of SourceBans Material Admin before version 1.1.6. Detection can focus on monitoring for unusual or crafted XAJAX calls or HTTP requests targeting this endpoint, especially those manipulating VK or Skype/Discord profile link fields.

Since the vulnerability can be exploited via CSRF combined with SQL injection, detection might include checking web server logs for suspicious GET or POST requests lacking valid CSRF tokens or containing suspicious payloads in profile link parameters.

Specific commands are not provided in the resources, but general approaches include:

• Review web server access logs for requests to includes/sb-callback.php or the ChangeAdminsInfos endpoint with unusual parameters.
• Use web application firewall (WAF) rules to detect and block SQL injection patterns in HTTP requests.
• Employ tools like curl or wget to simulate crafted requests and observe if the system responds abnormally or allows data manipulation.
• Monitor for unexpected changes in administrator account data or privilege levels.

Mitigation Strategies

The primary mitigation step is to update SourceBans Material Admin to version 1.1.6 or later, where this vulnerability has been patched.

If immediate updating is not possible, temporarily disabling the vulnerable ChangeAdminsInfos endpoint can reduce risk.

Additional mitigation measures include:

• Implement CSRF protection on all sensitive endpoints to prevent unauthorized requests.
• Harden input validation and escaping mechanisms to prevent SQL injection.
• Restrict access to the admin panel and sensitive endpoints to trusted IP addresses or networks.
• Monitor logs for suspicious activity and privilege escalations.
