CVE-2026-9451
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 · uneditedA weakness has been identified in code-projects Employee Management System 1.0. Affected by this vulnerability is an unknown functionality of the file /process/applyleaveprocess.php. This manipulation of the argument ID causes sql injection. The attack can be initiated remotely. The exploit has been made available to the public and could be used for attacks.
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 code-projects Employee Management System 1.0 allows remote attackers to inject malicious SQL queries via the ID parameter in /process/applyleaveprocess.php. The vulnerability is caused by unsanitized user input being directly incorporated into SQL queries, and public exploit availability increases attack likelihood.

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 application versionLocate the application files and check for version identifiers in the source code, README, or configuration files. Common paths include the root directory or a version.php file.Affected if The application is Employee Management System version 1.0 or an unpatched variant.
-
Verify applyleaveprocess.php existsCheck for the presence of the file at /process/applyleaveprocess.php in the web root directory.Affected if The file exists and is accessible via the web server.
-
Inspect the ID parameter handlingOpen applyleaveprocess.php and search for the ID parameter usage in SQL queries. Look for dynamic SQL construction where $_GET, $_POST, or $_REQUEST['ID'] is directly concatenated into SQL statements without sanitization or parameterized queries.Affected if The ID parameter is used in SQL queries without prepared statements, parameter binding, or input validation.
-
Test the vulnerabilitySend a crafted request to applyleaveprocess.php with the ID parameter containing SQL injection payloads (e.g., ID=1' OR '1'='1). Observe whether the application returns unexpected database errors or altered behavior.Affected if The application responds with SQL errors or returns data that differs from expected behavior based on the injected payload.
If Employee Management System 1.0 is deployed with the applyleaveprocess.php file accessible and the ID parameter is used in unparameterized SQL queries, the environment is affected by this SQL injection vulnerability.

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 dynamic SQL queries with prepared statements or parameterized queries for the ID parameter, and implement input validation across all application entry points to prevent similar vulnerabilities.
