CVE-2026-34104
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 name GET parameter directly into an unsanitized SQL query in designer.php (line 124): SELECT * FROM complex WHERE name='\".$_GET['name'].\"'. 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 confidenceSQL injection vulnerability in Guardian language-system's designer.php where the 'name' GET parameter is directly concatenated into an SQL query without sanitization (line 124), allowing authenticated attackers to inject arbitrary SQL commands 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.
-
Identify The Guardian language-system installation and versionLocate the product installation directory and check for version files (such as VERSION, version.php, or similar) or use package management tools if installed via package managerAffected if The installed version falls within the affected version range and the product is deployed
-
Locate designer.php in the installationSearch the web root or application directory for the file designer.php - typical paths may include /admin/, /designer/, or the main application directoryAffected if designer.php exists in the environment, indicating the vulnerable component is present
-
Inspect the SQL query at line 124 of designer.phpOpen designer.php and navigate to line 124 (or the relevant code section handling the 'name' parameter) to examine how the GET parameter is used in SQL queriesAffected if The code shows direct concatenation of the 'name' GET parameter into an SQL query without using parameterized queries, prepared statements, or input sanitization
-
Verify if authentication is required or enforcedCheck the authentication mechanism at the top of designer.php or in session handling code to determine if the endpoint requires valid credentialsAffected if Authentication is not properly enforced, or the SQL injection can be reached with valid user credentials (even low-privilege accounts)
-
Test the vulnerable parameter in a safe mannerIf authorized in a non-production environment, send a harmless GET request to designer.php with a test 'name' parameter value to observe if SQL syntax errors are reflected in the responseAffected if SQL error messages or unexpected database behavior is triggered by manipulating the 'name' parameter
The environment is affected if The Guardian language-system is deployed with the vulnerable designer.php file present, and the code at line 124 directly uses the 'name' GET parameter in SQL queries without parameterized queries or sanitization.

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 direct string concatenation with prepared statements/parameterized queries and implement proper input validation for all user-supplied parameters.
