CVE-2026-40829
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 · uneditedA high privileged remote attacker can exploit an unauthenticated SQL Injection vulnerability in the view.html.php files UpdateParam function due to improper neutralization of special elements in a SQL UPDATE command allowing for reading the whole database and changing values in 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 the UpdateParam function of view.html.php allows a high-privileged remote attacker to inject malicious SQL commands into an UPDATE query, enabling reading of the entire database and modification of non-critical table values.

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 the view.html.php file in your environmentSearch for view.html.php in your web application directory structure. Common locations include components/, modules/, or plugin directories.Affected if The file exists and contains an UpdateParam function definition
-
Inspect the UpdateParam function for SQL query constructionOpen view.html.php and locate the UpdateParam function. Examine how it builds SQL queries - look for string concatenation, string interpolation, or direct variable insertion into SQL statements.Affected if The function constructs UPDATE queries using string concatenation or interpolation with user-controlled input without proper escaping or parameterization
-
Check for prepared statements or parameter bindingIn the UpdateParam function, search for patterns like $db->quote(), $db->escape(), prepare(), bindParam(), or parameterized query calls. Also check for input sanitization functions.Affected if No parameterized queries (prepared statements) are used, and input is directly concatenated into the UPDATE SQL statement
-
Identify the parent component/applicationDetermine which component or application owns this view.html.php file by checking file headers, comments, or surrounding directory structure.Affected if The file belongs to a PHP-based web application component that has not been patched for this SQL injection vulnerability
You are affected if view.html.php with an UpdateParam function exists in your environment and that function builds SQL UPDATE queries through direct string concatenation without using prepared statements or proper input escaping.

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 (prepared statements) in the UpdateParam function to properly neutralize special SQL characters and prevent injection attacks.
