CVE-2026-34101

Guardian · language-system

Guardian language-system is vulnerable to error-based SQL injection via the 'id' GET parameter in text_file.php, allowing authenticated attackers to extract sensitive database contents.

Executive summary

An authenticated SQL injection vulnerability in the Guardian language-system poses a critical risk of unauthorized database data exfiltration.

Vulnerability

The application fails to sanitize the 'id' GET parameter before incorporating it into a SQL query within text_file.php. This allows an authenticated attacker to manipulate query logic and extract sensitive information from the backend database.

Business impact

Successful exploitation of this vulnerability allows an attacker to bypass data access controls and exfiltrate sensitive files and metadata stored in the database. Given the critical CVSS score of 9.8, this flaw represents a significant risk to data confidentiality and integrity, potentially leading to a complete compromise of the application's data layer.

Remediation

Immediate Action: Apply the latest security update provided by Guardian to address the SQL injection flaw in text_file.php.

Proactive Monitoring: Review application access logs for unusual patterns in GET requests to 'text_file.php', particularly those containing SQL syntax characters.

Compensating Controls: Deploy a Web Application Firewall (WAF) with rules configured to detect and block SQL injection payloads targeting the 'id' parameter.

Exploitation status

Public Exploit Available: No

Analyst recommendation

This vulnerability presents a critical risk to the security of your database environment. IT administrators must prioritize patching this specific component immediately. While the vulnerability requires authentication, the ease of exploitation once access is obtained necessitates urgent remediation to prevent unauthorized data access.
