CVE-2025-52833
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 · uneditedImproper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability in designthemes LMS lms allows SQL Injection.This issue affects LMS: from n/a through <= 9.2.
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 designthemes LMS allows attackers to inject malicious SQL commands through unsanitized user input. The flaw exists in the LMS component and affects versions up to and including 9.2, potentially enabling unauthorized database access, data exfiltration, or privilege escalation.

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 designthemes LMS installation and versionIdentify the designthemes LMS plugin/theme installation directory and locate its version file or header comment. Common locations include wp-content/plugins/ or themes/ directory if WordPress-based, or the application includes/version file.Affected if The installed version is 9.2 or lower (including any 9.x.x version below 9.2)
-
Confirm LMS component is activeCheck whether the LMS module/component is enabled in the designthemes installation. This may be visible in the admin dashboard, plugin activation list, or component configuration file.Affected if The LMS component is installed and enabled in the environment
-
Identify LMS user input endpointsInspect the LMS component code for PHP files that handle user-supplied input (GET/POST parameters) and pass them to database queries. Look for SQL query construction involving request variables without prepared statements.Affected if User input from HTTP requests (GET/POST) is directly concatenated into SQL queries within LMS files
-
Verify database interaction layerExamine the database abstraction layer used by LMS (e.g., $wpdb in WordPress, custom DB classes). Check if queries involving user input use parameterized queries/prepared statements or raw string concatenation.Affected if Database queries in LMS use raw string concatenation with user input rather than parameterized queries (prepared statements)
-
Check for unsanitized input in common LMS featuresReview common LMS functions such as course search, user registration, enrollment, quiz answers, or comment submissions for unsanitized input handling in SQL statements.Affected if Any user-controllable fields in course search, registration, enrollment, or quiz features feed directly into SQL without sanitization or parameterization
You are affected if designthemes LMS version 9.2 or lower is installed with the LMS component enabled and user input is processed through non-parameterized SQL 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 dataUpgrade to the latest patched version of designthemes LMS. Until a patch is available, implement input validation, sanitization, and use parameterized queries (prepared statements) for all database interactions.
