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 confidenceCross-site scripting (XSS) vulnerability in the /signup.php file of the Online-Book-Store-Website version 1.0. The 'name' parameter is not properly sanitized or encoded, allowing an attacker to inject malicious JavaScript code that executes in the context of other users' browsers.

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 the installed Online Bookstore versionLocate version information in the application - check for version.php, README files, or the footer/source code of the application. Also check if the source code repository or deployment files indicate version 1.0.Affected if The installed version is Keerti1924 Online Bookstore Website version 1.0
-
Locate the signup.php fileSearch the web root directory for the signup.php file - typically found in the application root or a /public/ directory.Affected if The signup.php file exists in the deployed application
-
Verify the 'name' parameter is processedInspect the signup.php source code to confirm the 'name' parameter from POST or GET requests is being received and used in the application logic.Affected if The signup.php file processes a 'name' parameter from user input
-
Check for missing output encodingReview the signup.php code where the 'name' parameter is displayed or output back to users (e.g., in forms, confirmation pages, admin panels). Look for absence of htmlspecialchars(), htmlentities(), or similar encoding functions.Affected if The 'name' value is output to HTML without proper sanitization or encoding functions
-
Test for XSS reflectionSubmit a test value like <script>alert(1)</script> as the 'name' parameter in a signup request and observe if the raw script tags appear in the response or execute in the browser.Affected if The submitted 'name' value is reflected in the response without encoding
A user is affected if they have deployed Keerti1924 Online Bookstore Website version 1.0 with the signup.php file accessible and the 'name' parameter being reflected in outputs without encoding.

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 input validation and output encoding for the 'name' parameter in signup.php. Use context-appropriate encoding when displaying user-supplied data and consider implementing a Content Security Policy (CSP) header.
