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 · unedited
OnlineNewsSite v1.0 is vulnerable to Cross Site Scripting (XSS) which allows attackers to execute arbitrary code via the Title and summary fields in the /admin/post/edit/ endpoint.

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 confidence

OnlineNewsSite v1.0 contains a stored Cross Site Scripting (XSS) vulnerability in the admin panel's post editing functionality at /admin/post/edit/. The Title and summary fields fail to properly sanitize user-supplied input, allowing authenticated attackers to inject malicious JavaScript code that executes when other users view the compromised content.

MitigationImplement robust input validation and output encoding for the Title and summary fields. Use a proper HTML sanitization library to strip dangerous tags and attributes before storing and before rendering user input, and consider adding a Content Security Policy header to provide defense-in-depth.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Confirm OnlineNewsSite v1.0 installation
    Locate the application source files or check the application's version identifier, typically found in a configuration file, README, or the application footer
    Affected if The installed version is OnlineNewsSite v1.0 or earlier
  2. Verify admin panel access exists
    Check if the /admin/post/edit/ endpoint is accessible by attempting to access it with valid admin credentials, or by inspecting routing configuration
    Affected if The endpoint is accessible and accepts authenticated requests
  3. Identify stored post data with unsanitized input
    Query the database or inspect stored posts to examine the Title and summary fields for any injected script tags or JavaScript event handlers
    Affected if The stored Title or summary content contains unescaped HTML tags such as <script>, <img>, or JavaScript event handlers like onload, onerror
  4. Inspect input sanitization in post edit code
    Review the server-side code handling /admin/post/edit/ requests to determine if the Title and summary fields undergo HTML encoding or sanitization before storage
    Affected if No input validation, encoding, or sanitization is performed on these fields before storing to database
  5. Check if rendered output escapes stored content
    View a post as a non-admin user and inspect the page source to see if the Title and summary fields are rendered with HTML entities encoded (e.g., &lt;script&gt;)
    Affected if The Title or summary fields render raw HTML/JavaScript without encoding when viewed by other users

You are affected if OnlineNewsSite v1.0 is running, the admin panel is accessible, and the Title or summary fields in /admin/post/edit/ are stored and rendered without sanitization or 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.

Mitigation

Implement robust input validation and output encoding for the Title and summary fields. Use a proper HTML sanitization library to strip dangerous tags and attributes before storing and before rendering user input, and consider adding a Content Security Policy header to provide defense-in-depth.
