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
member.php in MyBB (aka MyBulletinBoard), when debug mode is available, allows remote authenticated users to change the password of any account by providing the account's registered e-mail address in a debug request for a do_lostpw action, which prints the change password verification code in the debug output.

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

In MyBB (aka MyBulletinBoard), when debug mode is enabled, the member.php script allows any authenticated user to trigger a password reset for arbitrary accounts by submitting the target user's email address via a 'do_lostpw' debug request. The password reset verification code is then exposed in the debug output, enabling the attacker to complete the password change and hijack any account on the forum.

MitigationDisable debug mode in production MyBB installations; debug functionality should never be accessible on live systems. If available, apply vendor patches for this vulnerability.

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 MyBB version
    Locate the version file or admin panel version display in your MyBB installation and note the exact version number
    Affected if The installed version is exactly 1.2.5
  2. Confirm debug mode is enabled
    Check your MyBB configuration files (typically config.php) or settings area for the debug mode setting and determine if it is set to enabled or on
    Affected if Debug mode is currently enabled on the forum
  3. Verify member.php script exists
    Check for the presence of the member.php script in your MyBB web root directory
    Affected if The member.php script exists and is accessible on the server
  4. Test for debug password reset functionality
    As an authenticated user, attempt to access the debug password reset endpoint by submitting a do_lostpw request with a target email address; observe whether the system returns a password reset code in the response
    Affected if The do_lostpw debug request returns a password reset verification code in the output

You are affected if your MyBB installation is version 1.2.5 AND debug mode is currently enabled, as this combination allows authenticated users to reset arbitrary account passwords through the member.php debug functionality.
