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
TYPO3 is an open source PHP based web content management system. In versions 9.0.0 through 9.5.27, 10.0.0 through 10.4.17, and 11.0.0 through 11.3.0, user credentials may been logged as plain-text. This occurs when explicitly using log level debug, which is not the default configuration. TYPO3 versions 9.5.28, 10.4.18, 11.3.1 contain a patch for this vulnerability.

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

TYPO3 versions 9.x, 10.x, and 11.x log user credentials in plain-text when debug log level is explicitly enabled (non-default configuration), allowing credential exposure through debug logs.

MitigationUpgrade to TYPO3 versions 9.5.28, 10.4.18, or 11.3.1 which contain the patch, or ensure debug logging is disabled in production environments.

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 installed TYPO3 version
    Locate the VERSION file in the TYPO3 root directory, or check the 'version' value in typo3conf/LocalConfiguration.php under 'SYS', or access the TYPO3 Install Tool and view System Information
    Affected if The installed version falls within these ranges: 7.0.0-7.6.51, 8.0.0-8.7.40, 9.0.0-9.5.27, 10.0.0-10.4.17, or 11.0.0-11.3.0
  2. Verify debug logging is enabled
    Inspect the logging configuration in typoconf/LocalConfiguration.php (or AdditionalConfiguration.php) and look for the 'logLevel' setting under the logging configuration section
    Affected if The logLevel is set to 'debug' (or a numeric value of 0) rather than the default production level
  3. Check for credential logging configuration
    Examine the TYPO3 logging configuration for any logger settings that record authentication events, particularly in typo3conf/LocalConfiguration.php under the 'LOG' section
    Affected if Logger rules exist that write authentication data (such as login attempts or session tokens) and debug logging is simultaneously active

A system is affected if it runs a vulnerable TYPO3 version (within the ranges listed) AND has debug logging explicitly enabled in the configuration.

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.

From vendor data
Upgrade available Upgrade to a release after 11.3.0
Interim mitigation

Upgrade to TYPO3 versions 9.5.28, 10.4.18, or 11.3.1 which contain the patch, or ensure debug logging is disabled in production environments.
