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
Open redirect vulnerability in Booked versions prior to 3.3 allows a remote unauthenticated attacker to redirect a user to an arbitrary web site and conduct a phishing attack by having a user to access a specially crafted URL.

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

Open redirect vulnerability in Booked application allows unauthenticated remote attackers to craft malicious URLs that redirect users to arbitrary external websites. The vulnerability exists in versions prior to 3.3 due to insufficient validation of redirect parameters, enabling phishing attacks.

MitigationUpgrade Booked to version 3.3 or later which contains the security patch. If immediate upgrade is not possible, implement input validation on redirect parameters to ensure only trusted internal paths are allowed.

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 the installed Booked version
    Locate the version file or check the admin dashboard footer for the current version number. Common locations include a version.php file in the installation directory or the 'About' section in the admin panel.
    Affected if The installed version is lower than 3.3.0 (e.g., 3.2.x, 3.1.x, earlier versions)
  2. Verify unauthenticated access is possible
    Determine if the Booked application is accessible without login. Attempt to access the login page and public-facing reservation pages without authenticating.
    Affected if The application allows unauthenticated access to pages that accept redirect parameters
  3. Inspect redirect parameter handling
    Review the application source code or configuration for how redirect parameters (such as 'returnUrl', 'redirect', 'url', or similar) are processed. Look for validation logic that should restrict redirects to trusted internal paths.
    Affected if The application accepts redirect parameters without strict validation against an allowlist of internal paths, or validation is missing entirely
  4. Test for open redirect vulnerability
    Craft a test URL with a redirect parameter pointing to an external domain (e.g., https://example.com) and observe if the application redirects there without warning or validation message.
    Affected if The application redirects to the arbitrary external URL specified in the parameter without validating it is an internal path

Your environment is affected if Booked version is below 3.3.0 and the application processes redirect parameters without validating they point only to trusted internal paths.

Upgrade available Upgrade to 3.3.0 or later
Fixed in 3.3.0
Interim mitigation

Upgrade Booked to version 3.3 or later which contains the security patch. If immediate upgrade is not possible, implement input validation on redirect parameters to ensure only trusted internal paths are allowed.

Recommended fix Moderate confidence

3.3.0

  1. 1. Back up your current Booked installation and database before upgrading.
  2. 2. Download Booked version 3.3.0 or later from the official repository (www.bookedscheduler.com).
  3. 3. Review the upgrade instructions provided in the release notes.
  4. 4. Upload and extract the new version files to your server, replacing the existing installation.
  5. 5. Run any database migration scripts included in the upgrade package.
  6. 6. Verify the installation by logging in and testing the application functionality.
  7. 7. Test that the open redirect vulnerability is no longer present by attempting to access a crafted URL with a redirect parameter.
Caveat Review release notes for any configuration or feature changes between your current version and 3.3.0
