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
The OTP-less one tap Sign in plugin for WordPress is vulnerable to privilege escalation via account takeover in versions 2.0.14 to 2.0.59. This is due to the plugin not properly validating a user's identity prior to updating their details, like email. This makes it possible for unauthenticated attackers to change arbitrary users' email addresses, including administrators, and leverage that to reset the user's password and gain access to their account. Additionally, the plugin returns authentication cookies in the response, which can be used to access the account directly.

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

The OTP-less one tap Sign in plugin for WordPress fails to validate user identity before allowing email address updates, enabling unauthenticated attackers to modify any user's email—including administrators. Attackers can then trigger password resets to the new email and gain full account access, with the plugin additionally returning authentication cookies in the response for direct session hijacking.

MitigationUpdate the plugin to the latest version immediately. Review user accounts for unauthorized email changes and reset passwords for all administrator accounts as a precautionary measure.

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 if OTP-less plugin is installed
    Navigate to WordPress admin dashboard > Plugins and look for 'OTP-less One Tap Sign In' or check the plugins directory via file system for the otp-less folder
    Affected if The plugin is present in the WordPress installation
  2. Determine installed plugin version
    In WordPress admin > Plugins > Installed Plugins, find the OTP-less entry and note the version number displayed
    Affected if The installed version falls within any vulnerable version range (compare against official vulnerability advisory)
  3. Check for unauthorized email modifications
    In WordPress admin > Users, review the email address column for all user accounts, particularly administrators, and compare against known legitimate email addresses
    Affected if Any user account shows an email address that was not changed by the legitimate account owner
  4. Inspect user account audit logs
    If user logging plugins or WordPress activity logs are available, review recent user profile changes for unexpected email update events
    Affected if Recent email change events appear for users who did not make those changes
  5. Review for unexpected authentication sessions
    Check browser cookie storage or WordPress session tables for authentication cookies that may have been returned in plugin API responses
    Affected if Authentication cookies exist that were not obtained through normal login procedures

If the OTP-less plugin is installed and its version is within the vulnerable range, or if unauthorized email changes are detected in user accounts, the environment is likely affected.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Update the plugin to the latest version immediately. Review user accounts for unauthorized email changes and reset passwords for all administrator accounts as a precautionary measure.

Recommended fix High confidence

2.0.60 or later

  1. Update the OTP-less one tap Sign in plugin to version 2.0.60 or later
  2. After updating, verify that users with administrative privileges still have correct email addresses
  3. If any suspicious users were added or emails were changed, remove unauthorized accounts and restore legitimate administrator access
