CVE-2026-34099
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 job_info.php (line 16): SELECT * FROM jobs where id = '\".$_GET['id'].\"'. No authentication is required. An unauthenticated attacker can perform error-based SQL injection to extract the database version, current user, schema names, and table 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 confidenceGuardian language-system contains an unauthenticated SQL injection vulnerability in job_info.php where the id GET parameter is directly concatenated into an SQL query without sanitization or parameterized queries. An attacker can exploit this to inject arbitrary SQL commands and extract sensitive database information including version, current user, schema names, and table contents.

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 job_info.php fileSearch your web root directory for job_info.php using file system search or command: find /path/to/webroot -name "job_info.php"Affected if The file exists in your environment, indicating the potentially vulnerable component is present
-
Inspect the 'id' parameter handling in job_info.phpOpen job_info.php and search for code handling the 'id' GET parameter (look for $_GET['id'] or $_REQUEST['id'])Affected if The code directly uses the 'id' parameter in SQL queries without visible sanitization or prepared statements
-
Check for unsafe SQL concatenation patternsSearch the file for SQL query construction looking for patterns like: mysql_query, mysqli_query, or PDO::query where the 'id' variable is concatenated using dots (.) or string interpolationAffected if The 'id' parameter is concatenated directly into SQL strings (e.g., "SELECT * FROM... WHERE id='" . $_GET['id'] . "'") rather than using parameterized queries
-
Verify if input validation existsLook for input validation functions (filter_var, preg_match, intval type casting) applied to the 'id' parameter before SQL executionAffected if No input validation or sanitization is performed on the 'id' parameter before it is used in SQL queries, or validation is insufficient to prevent SQL injection
-
Confirm web application is exposedTest accessing job_info.php directly via HTTP request to your domain (e.g., GET /job_info.php?id=1)Affected if The file is accessible over the network without authentication, allowing remote exploitation
If job_info.php exists and the 'id' GET parameter is used in SQL queries through direct string concatenation without prepared statements or proper input validation, your environment is vulnerable to CVE-2026-34099.

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 prepared statements/parameterized queries, and implement proper input validation on the id parameter before using it in SQL queries.
