CVE-2026-42647
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 Beardev JoomSport allows Blind SQL Injection. This issue affects JoomSport: from n/a through 5.7.7.
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 · high confidenceA blind SQL injection vulnerability exists in the JoomSport component where unsanitized user input is directly incorporated into SQL queries. Attackers can exploit this to inject malicious SQL commands, potentially extracting sensitive data from the database or compromising the underlying system. The blind nature means the attacker infers information from application behavior rather than direct error output.

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.
-
Verify JoomSport component is installedAccess your Joomla administrator panel and navigate to Extensions > Manage, or check for the /components/com_joomsport/ directory on the web server filesystemAffected if The JoomSport component is present in the Joomla installation
-
Determine installed JoomSport versionCheck the version through Joomla's extension manager or inspect the joomsport.xml file typically located in /administrator/components/com_joomsport/ or /components/com_joomsport/Affected if The installed version is lower than 5.7.7 (the patched release)
-
Identify publicly accessible user input pointsReview the JoomSport component for pages that accept user parameters via GET or POST requests, particularly in search, filtering, or sorting functionalitiesAffected if The component accepts user-supplied parameters without apparent sanitization
-
Check for SQL injection sink locationsExamine the component source code files (particularly in models, controllers, or views folders) for direct use of $_GET, $_POST, or JRequest variables in SQL queries without using JDatabase's quote escaping or prepared statement methodsAffected if Code directly concatenates user input into SQL query strings without parameterization
-
Test for blind SQL injection behaviorIf you have authorized testing access, introduce time-delay SQL payloads (such as SLEEP() statements) into suspected input parameters and observe whether the application response is delayedAffected if Application response time increases based on injected SQL conditions, confirming blind SQL injection
-
Review database query logsEnable MySQL query logging and observe whether unexpected or malicious SQL syntax appears in logs originating from JoomSport component requestsAffected if Database logs show SQL queries with unexpected syntax or injection patterns tied to JoomSport endpoints
Your environment is affected if JoomSport is installed and the version is below 5.7.7, with unpatched user input handling in SQL queries present in the component.

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 dataApply vendor-supplied patch or upgrade to the latest JoomSport version beyond 5.7.7. If no patched version is available, implement parameterized queries (prepared statements) for all database operations and add input validation to sanitize special characters.
