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
A host header injection vulnerability in BookReviewLibrary 1.0 allows attackers to obtain the password reset token via user interaction with a crafted password reset link.

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

Host header injection in BookReviewLibrary 1.0 allows attackers to manipulate the Host header in password reset requests, causing the application to generate password reset links with attacker-controlled domains. When users click these crafted links, the password reset tokens are sent to the attacker-controlled server instead of the legitimate application.

MitigationImplement strict Host header validation and use hardcoded base URLs or absolute URIs for generating password reset links rather than trusting client-supplied Host headers.

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 BookReviewLibrary installation and version
    Locate the BookReviewLibrary application files (typically in web root or application directory). Check for version information in metadata files, about page, or application configuration (e.g., version.txt, info.php, or similar).
    Affected if The installed version is BookReviewLibrary 1.0 exactly or falls within the 1.0.x range.
  2. Identify password reset endpoint
    Locate the password reset functionality in the application. Search for files handling password reset requests (commonly named reset.php, forgot_password.php, or similar in the application directory).
    Affected if A password reset mechanism exists and is accessible.
  3. Examine Host header usage in reset link generation
    Open the password reset handler file and inspect the code that generates password reset links. Look for occurrences of $_SERVER['HTTP_HOST'], $_SERVER['HOST'], or similar server variables used to construct URLs.
    Affected if The code uses the client-supplied Host header (e.g., from HTTP request) to build password reset URLs without validation against an allowlist.
  4. Check for Host header validation
    Search the application code for Host header validation logic (functions that verify $_SERVER['HTTP_HOST'] against a whitelist, or configuration that hardcodes the base URL).
    Affected if No validation exists, and the application blindly trusts the Host header when generating reset links.
  5. Test behavior with manipulated Host header
    Send a password reset request with a modified Host header (e.g., Host: attacker.com) and observe if the generated reset link contains the attacker's domain.
    Affected if The password reset link in the response email or page reflects the manipulated Host header value instead of the legitimate application domain.

A user is affected if BookReviewLibrary 1.0 is running and the password reset functionality uses the Host header without validation to generate reset links.
