CVE-2025-27302
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 Claudio Adrian Marrero CHATLIVE chatlive allows SQL Injection.This issue affects CHATLIVE: from n/a through <= 2.0.1.
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 · high confidenceSQL injection vulnerability in CHATLIVE chat application allows attackers to inject malicious SQL commands through unsanitized user input. The vulnerability affects versions up to and including 2.0.1, enabling remote attackers to potentially access, modify, or delete database contents.

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 CHATLIVE installationSearch for CHATLIVE application files on the system. Check common web application directories (e.g., /var/www/, /home/*/public_html/, C:\inetpub\wwwroot\) or the application's installation directory for files named chatlive, CHATLIVE, or related components.Affected if CHATLIVE chat application is found installed on the system
-
Determine installed versionLocate version information in the CHATLIVE installation. Check for a version file, About page within the application, or configuration files that may contain version metadata. Compare the found version against 2.0.1.Affected if The installed version is 2.0.1 or lower (any version up to and including 2.0.1)
-
Verify user input functionality is enabledIdentify whether the CHATLIVE application exposes functionality that accepts user input (e.g., chat messages, user registration, search fields, comment forms). Determine if these input fields are accessible to remote users via web interface, API, or other network-accessible endpoints.Affected if The application accepts user input and is network-accessible (web-facing or API-exposed)
-
Review application logs for SQL injection indicatorsExamine CHATLIVE application logs and web server access/error logs for suspicious patterns such as SQL keywords (UNION, SELECT, INSERT, DROP, --), unusual database errors, or repeated failed queries that may indicate SQL injection testing.Affected if Logs show SQL injection attempts or unusual database error messages
-
Inspect database query handlingIf code access is available, review the CHATLIVE source code to verify whether database queries are constructed using string concatenation with user input versus parameterized queries or prepared statements. Focus on modules handling chat messages, user authentication, or search functionality.Affected if Code uses dynamic SQL queries with direct user input concatenation rather than parameterized queries
A system is affected if CHATLIVE version 2.0.1 or lower is installed and the application accepts user input that flows into database queries without proper sanitization or parameterized query implementation.

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 and implement proper input validation across all database interactions to prevent SQL injection attacks.
