CVE-2026-7741
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 · uneditedA vulnerability was detected in CodeAstro Online Classroom 1.0. Impacted is an unknown function of the file /OnlineClassroom/studentlogin. Performing a manipulation of the argument sid results in sql injection. Remote exploitation of the attack is possible. The exploit is now public and may be used.
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 CodeAstro Online Classroom 1.0 where the 'sid' parameter in the /OnlineClassroom/studentlogin endpoint fails to properly sanitize user input, allowing remote attackers to inject malicious SQL queries.

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 the CodeAstro Online Classroom installationSearch for files containing 'studentlogin' or 'OnlineClassroom' in the web server document root (e.g., /var/www/html, /www, C:\inetpub\wwwroot). Look for the studentlogin.php or studentlogin endpoint file.Affected if The CodeAstro Online Classroom application version 1.0 is found on the system.
-
Identify the studentlogin endpoint fileNavigate to the /OnlineClassroom/ directory and locate the studentlogin.php file or the routing configuration handling the /studentlogin route.Affected if The studentlogin endpoint file exists in the application.
-
Inspect the SQL query handling for the 'sid' parameterOpen the studentlogin endpoint source code. Search for SQL queries that incorporate the 'sid' parameter directly (e.g., SELECT * FROM ... WHERE sid='$sid' or similar string concatenation without parameter binding).Affected if The code constructs SQL queries by concatenating the 'sid' parameter directly without using prepared statements or parameter binding.
-
Verify the application version is 1.0Check for a version file, about page, or header/footer include that displays the application version. Common locations: version.php, footer.php, or config files in the application root.Affected if The installed version is CodeAstro Online Classroom 1.0.
-
Test the 'sid' parameter for SQL injection vulnerabilityIf authorized and in a test environment, send a crafted request to /OnlineClassroom/studentlogin with the 'sid' parameter set to a SQL injection payload (e.g., sid=1' OR '1'='1). Observe whether the application returns unexpected database errors or behaves differently than expected.Affected if The application responds to SQL injection payloads in the 'sid' parameter, indicating lack of input sanitization.
The system is affected if CodeAstro Online Classroom 1.0 is installed and the studentlogin endpoint uses dynamic SQL queries with the 'sid' parameter without parameterized queries or input validation.

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, implement proper input validation on the 'sid' parameter, and apply vendor security patches when available.
