CVE-2026-33616
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 unauthenticated remote attacker can exploit an unauthenticated blind SQL Injection vulnerability in the mb24api endpoint due to improper neutralization of special elements in a SQL SELECT command. This can result in a total loss of confidentiality.
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 confidenceAn unauthenticated blind SQL Injection vulnerability exists in the mb24api endpoint where special elements in SQL SELECT commands are not properly neutralized, allowing remote attackers to inject malicious SQL queries without authentication.

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 installed product versionLocate and inspect the Mbconnect24 or Mymbconnect24 installation to determine the exact version number. Common locations include the application GUI 'About' section, installation directory metadata, or the application's version information file.Affected if The installed version is Mbconnect24 or Mymbconnect24 at version 2.19.4 or lower.
-
Locate the mb24api endpointIdentify where the mb24api endpoint is hosted within your environment. This is typically exposed via the application's web interface configuration or API documentation.Affected if The mb24api endpoint exists and is accessible within the application.
-
Verify mb24api is network accessibleDetermine whether the mb24api endpoint is exposed to network access. Check firewall rules, application access controls, and web server configuration to see if the endpoint accepts remote connections.Affected if The mb24api endpoint is reachable from external or untrusted networks without authentication.
-
Confirm SQL input handling in mb24apiReview or test the mb24api endpoint to observe whether user-supplied input in SQL SELECT operations is being properly neutralized. This can be done by reviewing source code if available, or by observing application behavior with special SQL characters in requests.Affected if User input passed to SQL queries within mb24api is not sanitized, neutralized, or parameterized.
You are affected if your environment runs Mbconnect24 or Mymbconnect24 version 2.19.4 or lower AND the mb24api endpoint is accessible and processes user input into SQL queries without proper neutralization.

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 dataImplement parameterized queries or prepared statements to properly neutralize SQL special characters in all database operations within the mb24api endpoint.
