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
PunBB 1.2.9 does not require password entry when changing the e-mail address in an account's profile, which might allow an attacker to make an address change via a hijacked login session.

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 · moderate confidence

PunBB 1.2.9 lacks password verification when users change their e-mail address in the profile settings. An attacker who has obtained a valid session (via session hijacking, shared computer, or stolen session cookie) can modify the victim's email address without needing to re-authenticate, potentially enabling further attacks like password resets or account takeover.

MitigationImplement password re-verification for sensitive profile changes including email address modification. Alternatively, upgrade to a patched version of PunBB if available.

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 PunBB version
    Locate the version file or check the admin panel for the exact version number. Common locations include version.php or the footer of admin pages.
    Affected if The installed version is exactly 1.2.9 (the only affected version listed)
  2. Verify the profile email modification feature exists
    Check if the user profile functionality is accessible and includes email address change options. Look for profile.php or similar files handling user profile updates.
    Affected if The profile email change feature is present and enabled on the installation
  3. Inspect the profile update code for password verification
    Examine the source code that handles email address changes in the profile (typically in profile.php or user.php). Look for any password confirmation logic before allowing email modifications.
    Affected if The code does not require password re-verification when changing the email address field in user profiles
  4. Check for any custom modifications to email change logic
    Review any local modifications or patches applied to the standard PunBB profile handling code. Compare against the vanilla 1.2.9 release.
    Affected if No custom code has been added to enforce password verification before email changes

You are affected if you are running PunBB version 1.2.9 with the profile email change feature enabled and the code lacks password verification logic for sensitive profile modifications.
