CVE-2026-40812
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 getLiveValues functions sn parameter 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 getLiveValues function's 'sn' parameter due to improper neutralization of special elements in a SQL SELECT command. This allows arbitrary SQL code execution leading to total loss of confidentiality.

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 using getLiveValuesSearch your codebase or deployed web application for the 'getLiveValues' function definition. Review application architecture documentation or source code to determine which product/component contains this function.Affected if Your deployed software includes a getLiveValues function that processes the 'sn' parameter in a SQL query.
-
Determine if getLiveValues is exposed via web/APIReview your web server logs, API endpoint documentation, or application routing configuration to identify if getLiveValues is accessible through HTTP/HTTPS endpoints. Check for routes, handlers, or controllers that invoke this function.Affected if The getLiveValues function is accessible as a web service endpoint or API that accepts external requests.
-
Inspect the 'sn' parameter handlingExamine the source code for getLiveValues to see how the 'sn' parameter is processed. Look for direct insertion of the 'sn' parameter value into SQL query strings without using parameterized queries, prepared statements, or proper escaping.Affected if The 'sn' parameter is concatenated directly into a SQL SELECT statement without parameterized binding or input validation.
-
Verify input validation on 'sn'Search the codebase for validation routines, allowlist checks, or sanitization functions applied to the 'sn' parameter before its use in database queries. Check if type checking, length limits, or pattern matching is enforced.Affected if No input validation, type checking, or allowlist constraints are applied to the 'sn' parameter before database execution.
-
Check for dynamic SQL usageReview the getLiveValues function code to determine if SQL queries are constructed using string concatenation or string formatting with user input rather than parameterized queries or an ORM with proper query building.Affected if The application builds SQL queries dynamically using string concatenation with the 'sn' parameter value.
You are affected if your environment runs software containing the getLiveValues function with the 'sn' parameter that is exposed to untrusted input and processes it via dynamic SQL without validation or parameterized queries.

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 to properly neutralize special characters in user input, and implement input validation for the 'sn' parameter.
