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.

Cross-Site Request Forgery (CSRF) vulnerability in priyanshumittal Bluestreet bluestreet allows Cross Site Request Forgery.This issue affects Bluestreet: from n/a through <= 1.7.3.

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 · low confidence

Cross-Site Request Forgery (CSRF) vulnerability in the Bluestreet application (versions up to and including 1.7.3) allows remote attackers to execute unauthorized state-changing operations on behalf of authenticated users by tricking them into visiting malicious pages or clicking crafted links.

MitigationImplement anti-CSRF tokens (synchronizer token pattern) for all state-changing operations and validate Origin/Referer headers on server-side to ensure requests originate from legitimate sources.

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. Identify Bluestreet installation
    Locate the Bluestreet application by checking for its web interface, installed files, or running processes. Look for the application responding on typical ports or the presence of Bluestreet-specific directories and files.
    Affected if Bluestreet is present in the environment
  2. Determine installed version
    Check the application's version by reviewing version files, examining the login page source, checking API endpoints that expose version information, or accessing admin/about pages that typically display version details.
    Affected if The installed version is 1.7.3 or lower
  3. Identify state-changing operations
    Review the application for endpoints that perform actions: user management, data modification, configuration changes, payment processing, or any operation that alters system state.
    Affected if The application has functional areas that modify data or settings
  4. Inspect forms for anti-CSRF tokens
    Examine the HTML source of forms that perform state-changing operations. Look within form tags for a hidden input field containing a random token value (commonly named 'csrf_token', 'token', '_token', or similar) that is submitted with the form.
    Affected if State-changing forms lack anti-CSRF token fields in their HTML markup
  5. Verify token validation on server-side
    Test by submitting a state-changing request without the anti-CSRF token (or with an invalid token) and observe whether the server accepts or rejects the request.
    Affected if The server accepts requests without valid anti-CSRF tokens

A user is affected if Bluestreet version 1.7.3 or lower is running AND state-changing forms lack anti-CSRF token protection, allowing attackers to trigger unauthorized actions on behalf of authenticated users.
