CVE-2026-4104
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 · uneditedAuthorization bypass through User-Controlled SQL primary key vulnerability in Akmer Informatics Automation Industry and Trade Ltd. Co. TeknoPass allows SQL Injection. This issue affects TeknoPass: from 20210501 through 20260429.
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 · moderate confidenceSQL injection vulnerability in TeknoPass allows attackers to inject malicious SQL code through user-controlled primary key values in SQL queries. The application directly uses user input in primary key lookups without proper sanitization or parameterized queries, bypassing authorization controls.

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 TeknoPass versionLocate the TeknoPass installation directory and check for a version file,About page, or use any available version command/utility provided by the applicationAffected if The installed version falls within the range 20210501 to 20260429 (inclusive)
-
Verify database connectivityConfirm that TeknoPass is configured to use a database backend (SQLite, MySQL, PostgreSQL, or other)Affected if A database is in use, as the SQL injection flaw targets database query handling
-
Inspect primary key parameter handlingReview application configuration files, request handling code, or API endpoints that process primary key values in database lookupsAffected if The application accepts primary key values from user input (HTTP parameters, API arguments, or form data) without using parameterized queries
-
Check for exposed query interfacesExamine if there are publicly accessible pages, APIs, or administrative endpoints that include primary key values in URLs or form submissionsAffected if User-accessible interfaces accept and process primary key parameters directly in database queries
-
Review application logsSearch TeknoPass logs for suspicious SQL syntax, database errors, or unusual query patterns indicating injection attemptsAffected if SQL errors or anomalous database queries appear in logs, suggesting active exploitation or vulnerable code execution
A user is affected if TeknoPass version 20210501 through 20260429 is installed and the application processes user-controlled primary key values in database queries through non-parameterized 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 direct string concatenation in SQL queries with parameterized queries/prepared statements. Implement proper input validation for primary key values and apply principle of least privilege to database accounts.
