CVE-2026-40833
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 dash.php files saveDashboardLayout function due to improper neutralization of special elements in a SQL INSERT command allowing for reading the whole database and inserting entries into a non critical table. This can result in a total loss of confidentiality and some loss of integrity.
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 confidenceSQL Injection vulnerability in dash.php's saveDashboardLayout function allows an unauthenticated attacker to inject malicious SQL via INSERT commands, enabling full database reads and arbitrary data insertion into a non-critical table.

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 dash.php in the environmentSearch for dash.php in web-accessible directories, commonly in /var/www/html, /app, or application root directories using: find / -name 'dash.php' 2>/dev/nullAffected if The file dash.php exists in the application filesystem
-
Verify saveDashboardLayout function existsOpen dash.php and search for 'function saveDashboardLayout' to confirm the function is definedAffected if The saveDashboardLayout function is present in dash.php
-
Inspect SQL query construction in saveDashboardLayoutExamine the function body for INSERT statements with string concatenation or interpolation (e.g., "INSERT INTO ... VALUES ('" . $var . "')" or "INSERT INTO ... VALUES ('$var')") rather than parameterized queriesAffected if INSERT statements use string concatenation/interpolation with user-supplied input without prepared statements or binding
-
Confirm function is accessible without authenticationCheck if saveDashboardLayout is called directly or reachable without session validation, authentication checks, or CSRF token validation at the entry pointAffected if The function can be invoked by unauthenticated users (no login/session check blocks access)
-
Identify user-controlled input sourcesLook for $_GET, $_POST, or $_REQUEST parameters being passed into the INSERT query within this functionAffected if User-supplied request parameters are directly incorporated into SQL queries without sanitization
Affected if dash.php with saveDashboardLayout function exists, uses dynamic SQL in INSERT statements, and is reachable by unauthenticated users with user input flowing directly into the 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/prepared statements in the saveDashboardLayout function and implement input validation to prevent SQL injection attacks.
