CVE-2026-40838
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 low privileged remote attacker can exploit an unauthenticated SQL Injection vulnerability in the getDeviceScalings 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 confidenceA SQL injection vulnerability exists in the getDeviceScalings function where user-supplied input is not properly sanitized before being used in a SQL SELECT query. An unauthenticated remote attacker can inject malicious SQL commands to extract sensitive data from the database, resulting in 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 software containing getDeviceScalings functionSearch your codebase or application deployment for files containing the string 'getDeviceScalings'. This may be in source code, compiled binaries, or libraries. Note the exact product name and version if found.Affected if The software in use contains a getDeviceScalings function that processes user input into SQL queries
-
Check application versionDetermine the installed version of the identified product. Compare against any version information you can obtain. There is no public CPE data for this CVE, so treat any version with the getDeviceScalings function as potentially affected unless the vendor has confirmed otherwise.Affected if The installed version includes the getDeviceScalings function
-
Inspect getDeviceScalings for dynamic SQLExamine the source code or decompiled code of the getDeviceScalings function. Look for SQL query construction that concatenates or embeds user-supplied parameters directly into the query string (for example, using string concatenation or string formatting to build SELECT statements).Affected if The function builds SQL queries using string concatenation or interpolation with user input rather than parameterized queries or prepared statements
-
Verify user input reaches the functionTrace the data flow from HTTP requests, API inputs, or other user-facing interfaces to the getDeviceScalings function call. Determine whether parameters like device identifiers, scaling values, or similar inputs are passed directly to the SQL query without sanitization.Affected if User-supplied parameters from external requests flow into the getDeviceScalings function without input validation or parameterization
-
Monitor database for anomalous SQL patternsReview database query logs or enable SQL statement logging. Look for unusual SELECT statements within or near the getDeviceScalings context that contain SQL operators like UNION, Boolean conditions (AND/OR), or comment syntax that may indicate injection attempts.Affected if Database logs show SQL queries with unexpected operators or syntax that suggest injection has occurred
Your environment is affected if the software in use contains the getDeviceScalings function that constructs SQL queries using unsanitized user input from external sources.

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 getDeviceScalings function to prevent SQL injection. Alternatively, implement input validation and use stored procedures with parameterized inputs.
