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
An issue was discovered in Joomla! Core before 3.8.8. The web install application would autofill password fields after either a form validation error or navigating to a previous install step, and display the plaintext password for the administrator account at the confirmation screen.

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 Joomla! web installer before version 3.8.8 contained a vulnerability where password fields for the administrator account were autofilled after form validation errors or when navigating back to previous installation steps. The plaintext password was then displayed on the confirmation screen, exposing sensitive credentials in the user interface.

MitigationUpgrade Joomla! Core to version 3.8.8 or later to remediate 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. Check Joomla! core version
    Access the Joomla! administrator panel and navigate to Help > System Information, or inspect the file /libraries/cms.php or /libraries/src/Version.php to find the version string
    Affected if The installed version is lower than 3.8.8 (for example, 3.8.7, 3.8.6, 3.8.0, or any 3.x version below 3.8.8)
  2. Verify installation method
    Determine whether the site was installed or reinstalled using the Joomla! web installer, which is the only installation method affected by this vulnerability
    Affected if The site was installed using the web-based installer and the version is below 3.8.8
  3. Confirm installer directory presence
    Check for the existence of the /installation directory at the Joomla! root. This directory is required for the web installer to run
    Affected if The /installation directory still exists and the Joomla! version is below 3.8.8, indicating the installer could potentially be re-run

The environment is affected if the installed Joomla! core version is below 3.8.8 and the web installer was used during initial setup or reinstallation.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

Fixed in 3.8.8
Interim mitigation

Upgrade Joomla! Core to version 3.8.8 or later to remediate this vulnerability.

Recommended fix High confidence

Joomla! 3.8.8 or later

  1. Back up your current Joomla! installation and database before proceeding with any upgrade
  2. Download Joomla! 3.8.8 or a later stable release from the official Joomla! website (https://www.joomla.org)
  3. Upgrade your Joomla! installation using either the built-in Joomla! Update component or by performing a standard Joomla! upgrade procedure
  4. Verify the administrator account can log in successfully after the upgrade
  5. Confirm the installation process no longer displays plaintext passwords at any step
Caveat Standard Joomla! minor version upgrades typically have minimal breaking changes; ensure backups and test in a staging environment first
