CVE-2026-40846
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 system view 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 · moderate confidenceAn unauthenticated SQL Injection vulnerability exists in a system view where user-supplied input is not properly neutralized before being used in a SQL SELECT command. This allows a low-privileged remote attacker to inject malicious SQL statements, potentially accessing sensitive data across 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.
-
Identify accessible system views that accept user inputReview application endpoints and database views that are exposed to unauthenticated users. Check which system views process URL parameters, query string arguments, or form submissions.Affected if A system view is accessible remotely and processes user-supplied input without authentication
-
Locate SQL query code within the vulnerable viewSearch application source code for SQL SELECT statements within system view handlers. Look for dynamic query construction that incorporates user input directly into the query string.Affected if User input is concatenated directly into SQL SELECT statements without sanitization
-
Verify input validation and sanitizationExamine the code path from user input to SQL execution. Check if parameterized queries, prepared statements, or input escaping functions are used before executing the SQL query.Affected if No parameterized queries or input escaping are implemented for the SQL query in the system view
-
Confirm database account privilegesIdentify the database credentials used by the application for the system view connection. Review what database-level permissions this account has (SELECT, INSERT, UPDATE, DELETE, schema access).Affected if The application database account has elevated privileges or access to sensitive schemas beyond what is strictly required for the view's function
-
Test for SQL injection vulnerabilityIf the system view is accessible and handles parameters, submit single-quote characters and common SQL injection payloads in query parameters. Compare application responses for error indicators or unexpected behavior.Affected if The application returns database errors, displays unexpected data, or behaves differently when special SQL characters are submitted in parameters
Your environment is affected if an unauthenticated system view processes user input without parameterized queries, allowing SQL injection.

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 for all database queries, especially in system views. Apply least-privilege principles to database accounts to limit the impact of successful SQL injection attacks.
