CVE-2025-52821
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 thanhtungtnt Video List Manager video-list-manager allows SQL Injection.This issue affects Video List Manager: from n/a through <= 1.7.
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 thanhtungtnt Video List Manager allows attackers to inject malicious SQL commands through unsanitized user input, potentially enabling unauthorized data access, modification, or deletion 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 Video List Manager installationSearch for files or directories named 'Video List Manager' or 'thanhtungtnt' in the web root, application directories, or installed packages on the server.Affected if The thanhtungtnt Video List Manager application is present on the system.
-
Determine the installed versionCheck the application's source code for version information, typically in a README, composer.json, package.json, or version file. Compare against any vendor-provided version list.Affected if The installed version cannot be determined or falls within an unpatched version range.
-
Locate database interaction codeSearch the application source for SQL query construction, looking for files that handle database connections and queries (commonly in PHP, Python, or Node.js files depending on the technology stack).Affected if Database operations are performed by the application.
-
Inspect user input handling in SQL queriesExamine how user-supplied input flows into SQL statements. Look for direct string concatenation or string interpolation in query construction without the use of parameterized queries or prepared statements.Affected if User input is directly concatenated into SQL queries without sanitization or parameterization.
-
Verify input validation mechanismsReview the codebase for input validation or sanitization functions applied to user input before it is used in database queries. Check if whitelist validation or input escaping is implemented.Affected if No input validation, sanitization, or escaping is performed on user input before database queries, or the sanitization is incomplete.
The system is affected if the thanhtungtnt Video List Manager is installed and user input is used in SQL queries without parameterized statements or proper input sanitization.

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) for all database operations and validate/sanitize user inputs before constructing SQL queries. If a patched version is available from the vendor, upgrade to that version.
