CVE-2026-40814
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 SQL Injection vulnerability in the dataapi.php files _mb24confi_getTagAlarm function 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 remote attacker can exploit a SQL Injection vulnerability in the _mb24confi_getTagAlarm function within dataapi.php. The vulnerability stems from improper neutralization of special elements in SQL SELECT commands, allowing attackers to inject malicious SQL statements and potentially extract sensitive data from the database.

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.
-
Locate the dataapi.php fileSearch the web root directory for the file 'dataapi.php' using file system tools (e.g., find /var/www -name dataapi.php or locate dataapi.php)Affected if The file dataapi.php exists in the application directory structure
-
Verify the _mb24confi_getTagAlarm function existsOpen dataapi.php and search for the function definition '_mb24confi_getTagAlarm' within the file contentAffected if The function _mb24confi_getTagAlarm is present in dataapi.php
-
Identify the product versionCheck version files, composer.json, or application admin panel for the installed software versionAffected if The installed version falls within the vulnerable version range for this product
-
Inspect SQL query patterns in the functionExamine the _mb24confi_getTagAlarm function code for dynamic SQL construction (string concatenation or interpolation into SQL queries without parameterized queries or prepared statements)Affected if The function constructs SQL queries using user input without proper parameterization or escaping
-
Assess network accessibility of the endpointDetermine if dataapi.php is accessible over the network without authentication by attempting to access the URL endpoint or reviewing web server access logsAffected if The dataapi.php endpoint is exposed and reachable without authentication
The environment is affected if dataapi.php with the vulnerable _mb24confi_getTagAlarm function exists, uses dynamic SQL without parameterization, and is network-accessible without authentication.

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 parameterized queries or prepared statements in the _mb24confi_getTagAlarm function to properly neutralize user input before database execution, or apply vendor-provided patches if available.
