CVE-2026-34101
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedGuardian language-system passes the id GET parameter directly into an unsanitized SQL query in text_file.php (line 17): SELECT id, filename, extension, type, duration, owner, private FROM files where id = '\".$_GET['id'].\"'. An authenticated attacker can perform error-based SQL injection to extract database contents.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThe Guardian language-system contains a SQL injection vulnerability in text_file.php where the 'id' GET parameter is directly concatenated into a SQL query without sanitization or parameterization. An authenticated attacker can inject malicious SQL code through the id parameter to extract sensitive database contents via error-based SQL injection.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Locate the Guardian language-system installationSearch for files or directories named 'guardian' or 'language-system' on the server, or check web server document roots for applications with similar namingAffected if The Guardian language-system is present in the environment
-
Find the vulnerable text_file.php fileLocate the text_file.php script within the Guardian language-system directory structureAffected if The file text_file.php exists in the application
-
Inspect the SQL query handling in text_file.phpOpen text_file.php and search for SQL query code, specifically looking for the 'id' GET parameter being used directly in query strings without prepared statements or parameterizationAffected if The code shows direct concatenation of the 'id' parameter into SQL queries without sanitization or parameterized queries
-
Verify the application is network-accessibleTest if the Guardian language-system web interface is reachable over the networkAffected if The application is exposed and accessible remotely
-
Confirm authentication is enabledCheck if the application requires authentication for access, as the vulnerability requires an authenticated attackerAffected if Authentication is configured and the application accepts logins, allowing a valid user to reach the vulnerable parameter
The environment is affected if the Guardian language-system is installed, text_file.php exists with direct SQL concatenation of the id parameter, and the application is accessible to an authenticated user.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataReplace the direct string concatenation with parameterized queries (prepared statements) using PDO or mysqli, ensuring all user input is properly bound as parameters rather than interpolated into SQL strings.
