CVE-2026-53690
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 · uneditedAn SQL Injection vulnerability exists in Redeight CMS version 1.0 via the "userEmail" parameter in the POST "/admin/index.php" login endpoint. The application fails to sanitize user input and directly interpolates it into SQL queries without using prepared statements, which allows unauthenticated remote attackers to execute arbitrary SQL commands and extract sensitive database information.
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 confidenceA critical SQL Injection vulnerability in Redeight CMS v1.0 allows unauthenticated attackers to inject arbitrary SQL commands via the userEmail parameter in the admin login form (/admin/index.php). The application directly interpolates user input into SQL queries without parameterized statements, enabling full database compromise.

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 Redeight CMS installationSearch the web root for Redeight CMS files, specifically looking for /admin/index.php or version indicators like readme.txt, changelog, or a version definition fileAffected if Redeight CMS v1.0 is present on the server
-
Locate the admin login endpointVerify the existence of /admin/index.php in the web directory and confirm it contains a login form with a userEmail input fieldAffected if The file /admin/index.php exists and accepts userEmail parameter
-
Inspect login SQL query logicExamine the PHP source code in /admin/index.php (or included files) for SQL query execution involving the userEmail parameter. Look for patterns like mysql_query, mysqli_query, or PDO::query with string concatenation or interpolation of $_POST['userEmail'] or $_REQUEST['userEmail']Affected if The code directly builds SQL queries by concatenating or interpolating the userEmail input without using prepared statements or parameter binding
-
Confirm absence of prepared statementsSearch the login code for mysqli_prepare, PDO::prepare, or parameterized query patterns. If none are found and the userEmail value appears directly in the query string, the vulnerability is presentAffected if SQL queries with userEmail are executed without prepared statement parameter binding
A user is affected if Redeight CMS v1.0 is installed and the admin login code at /admin/index.php uses direct string interpolation of the userEmail parameter into SQL queries instead of parameterized prepared statements.

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 all dynamic SQL queries in the login endpoint with parameterized queries/prepared statements, implement input validation, and apply principle of least privilege to the database user account.
