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 · unedited
Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability in TeconceTheme Nestbyte Core nestbyte-core allows Blind SQL Injection.This issue affects Nestbyte Core: from n/a through <= 1.2.

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 confidence

A blind SQL injection vulnerability exists in TeconceTheme Nestbyte Core (nestbyte-core) version 1.2 and earlier. The vulnerability allows unauthenticated attackers to inject malicious SQL queries through user-supplied input that is not properly sanitized before being used in database queries. Blind SQL injection means the attacker cannot see direct query output but can infer information by observing application behavior differences between true and false conditions.

MitigationUpgrade to a patched version of Nestbyte Core if available; otherwise, identify and sanitize all user input in database queries by implementing parameterized queries (prepared statements), validate all input strictly, and apply output encoding.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Confirm Nestbyte Core installation
    Locate the nestbyte-core plugin/theme package in your web application directory. Check for files named 'nestbyte-core' or similar, typically found in wp-content/plugins/ (WordPress), themes/, or vendor/ directories.
    Affected if The nestbyte-core package is present in the environment
  2. Determine installed version
    Check the version information in the package.json, plugin header, or README file within the nestbyte-core directory. Look for a 'version' field or changelog indicating the release version.
    Affected if The version is 1.2 or earlier, or the version cannot be determined (treat as potentially affected)
  3. Identify database-connected features
    Review the nestbyte-core source code for any files handling database queries, especially files that accept user input such as search functions, filters, forms, or API endpoints. Look for direct SQL query construction without prepared statements.
    Affected if The plugin/theme processes user input in database queries using string concatenation or unsanitized variables
  4. Test for SQL injection vulnerability
    If accessible, observe application behavior when submitting special SQL characters (quotes, semicolons) in user-facing input fields. Blind SQL injection may cause different response times, error messages, or application behavior between true/false conditions (e.g., adding AND 1=1 vs AND 1=2).
    Affected if Application exhibits different behavior based on injected SQL syntax, indicating unsanitized input is processed in SQL queries
  5. Review web server logs
    Examine HTTP access logs for unusual SQL syntax in request parameters targeting nestbyte-core endpoints. Look for patterns like quotes, UNION, SELECT, or boolean operators in query parameters.
    Affected if Logs show SQL metacharacters or query fragments in user-supplied parameters
  6. Check authentication requirements
    Verify whether the vulnerable endpoints are accessible without authentication. The CVE states unauthenticated attackers can exploit this flaw.
    Affected if Database interaction endpoints accept requests without requiring authentication

Your environment is affected if nestbyte-core version 1.2 or earlier is installed AND user input is processed in unsanitized database queries without parameterized statements.
