CVE-2026-40835
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 saveObjectFromData 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 · moderate confidenceA SQL Injection vulnerability exists in the saveObjectFromData function where user-supplied input is not properly sanitized before being used in a SQL SELECT query. An unauthenticated, low-privileged remote attacker can exploit this by injecting malicious SQL statements through input parameters, potentially exposing sensitive data from 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 the application and its installed versionLocate the software's version identifier through its web interface, CLI help command, or version file (check common locations like /VERSION, about page, or `app --version`)Affected if The installed version cannot be determined or is unknown compared to any official advisory ranges
-
Verify the saveObjectFromData function is accessibleIdentify if there are API endpoints, web routes, or services that invoke saveObjectFromData - review source code, API documentation, or network traffic for this function nameAffected if The function is exposed via any unauthenticated or low-privilege accessible endpoint
-
Confirm user input reaches the database queryTest the application's input parameters (forms, API calls, query strings) that feed into saveObjectFromData by reviewing code paths or testing with benign SQL charactersAffected if User-controllable input is directly concatenated into SELECT queries without visible sanitization or parameterization
-
Check database user privilegesReview the database credentials used by the application - examine configuration files, environment variables, or connection strings for the service accountAffected if The application database user has permissions beyond SELECT (such as WRITE access) or is not configured with least privilege
You are affected if the saveObjectFromData function is exposed to unauthenticated or low-privilege users and user input flows directly into SQL SELECT queries without parameterized query protection.

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 to properly neutralize special characters in user input before constructing SQL queries. Validate and whitelist input where possible, and apply principle of least privilege to database accounts.
