CVE-2026-40815
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 _mb24api_getUserAccount 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 _mb24api_getUserAccount function through improper neutralization of special elements in a SQL SELECT command, allowing complete unauthorized access to sensitive data.

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 vulnerable function in codebaseSearch source code files for the string '_mb24api_getUserAccount' to identify if this function exists in your applicationAffected if The function is present in your codebase and processes user input
-
Check if function handles user input directlyInspect the function implementation to see if it accepts parameters (such as user account identifiers) without sanitization before using them in SQL queriesAffected if User-provided parameters are directly concatenated into SQL SELECT statements without parameterized queries or input validation
-
Verify API endpoint exposureCheck API routing configuration to determine if the endpoint exposing _mb24api_getUserAccount is accessible without authenticationAffected if The API endpoint does not require authentication or authorization checks before executing the function
-
Test for SQL injection entry pointSend a crafted request to the API endpoint with SQL special characters (such as single quotes, UNION statements, or boolean-based payloads) in the user account parameterAffected if The application returns database error messages or exhibits different behavior indicating SQL query manipulation
-
Review SQL query implementationExamine all SQL queries within the _mb24api_getUserAccount function to confirm they use string concatenation or unparameterized queries instead of prepared statementsAffected if SQL queries are constructed by concatenating user input directly into the query string
Your environment is affected if the _mb24api_getUserAccount function exists in your codebase, is exposed via an unauthenticated API endpoint, and processes user input into SQL queries without using parameterized queries or 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 dataImplement parameterized queries or prepared statements in the _mb24api_getUserAccount function to properly neutralize SQL special characters in user input.
