CVE-2026-40813
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 tagid 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 SQL Injection vulnerability exists in the getLiveValues function's tagid parameter. Attackers can inject malicious SQL commands through unsanitized input in a SELECT statement, potentially allowing complete database compromise and unauthorized data access.

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 with getLiveValues functionSearch your codebase or application files for the string 'getLiveValues' to locate the vulnerable function. This is typically found in backend code handling live data or monitoring features.Affected if Your application contains a function named getLiveValues and exposes it via a web endpoint
-
Locate the tagid parameter exposureFind where getLiveValues is called and examine the HTTP request handling. Look for API endpoints, web services, or data feeds that accept a 'tagid' parameter.Affected if The tagid parameter is passed to getLiveValues via HTTP request without authentication requirements
-
Verify unauthenticated access is possibleCheck the authentication/authorization configuration for the endpoint handling getLiveValues. Attempt to access the endpoint without credentials to confirm it accepts unauthenticated requests.Affected if The endpoint accepting tagid input can be accessed without any authentication or session token
-
Inspect SQL query implementation for tagidExamine the getLiveValues function source code to see how the tagid parameter is incorporated into SQL queries. Look for direct string concatenation or unsanitized query building.Affected if The tagid parameter is used directly in a SQL SELECT statement without parameterized queries or input sanitization
-
Check input validation on tagid parameterReview any input validation, sanitization, or filtering code applied to the tagid parameter before it reaches the SQL query. Look for whitelisting, escaping, or type checking.Affected if No input validation exists or validation can be bypassed, allowing SQL metacharacters in the tagid parameter
Your environment is affected if your application exposes the getLiveValues function via an unauthenticated endpoint that uses the tagid parameter directly in SQL queries without parameterized preparation or proper input sanitization.

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/prepared statements for the tagid parameter, implement strict input validation, and apply least-privilege principles to database accounts. A WAF can serve as an interim control.
