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
A flaw has been identified in Moodle where, on certain sites, unauthenticated users could retrieve sensitive user data—including names, contact information, and hashed passwords—via stack traces returned by specific API calls. Sites with PHP configured with zend.exception_ignore_args = 1 in the php.ini file are not affected by 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

In Moodle, unauthenticated users can retrieve sensitive user data—including names, contact information, and hashed passwords—through stack traces returned by specific API calls. This occurs because PHP stack traces by default include function arguments, which can expose sensitive data. Sites with PHP configured with zend.exception_ignore_args = 1 are not affected.

MitigationConfigure PHP with zend.exception_ignore_args = 1 in php.ini to prevent stack traces from exposing sensitive information in error messages.

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 Moodle version
    Locate the version.php file in your Moodle installation directory (typically in the root or lib/ folder) and read the $release or $version variable, or use the Site Administration > Server > Environment page to view the installed version.
    Affected if The installed version is >= 4.5.0 and < 4.5.3
  2. Verify PHP zend.exception_ignore_args setting
    Check your PHP configuration (php.ini) for the zend.exception_ignore_args directive, or run 'php -i' or 'php -r "echo ini_get('zend.exception_ignore_args');"' to see the current value.
    Affected if The directive is absent, set to 0, or not explicitly set to 1 (the default PHP behavior exposes function arguments in stack traces)

You are affected if your Moodle version is between 4.5.0 and 4.5.3 (exclusive) AND your PHP configuration does not have zend.exception_ignore_args = 1 enabled.

Generated from the published advisory. Verify against your own configuration.

Check your environment

Paste your version and any relevant configuration and it will be compared against the affected criteria above. Do not include secrets or credentials.

AI-assisted, checked against the advisory. Informational, not a guarantee.

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.

dbcve · scoped
Upgrade available Upgrade to 4.5.3 or later
Fixed in 4.5.3
Interim mitigation

Configure PHP with zend.exception_ignore_args = 1 in php.ini to prevent stack traces from exposing sensitive information in error messages.

Recommended fix High confidence

Moodle 4.5.3

  1. Upgrade Moodle to version 4.5.3 or later to receive the security fix
  2. Verify the upgrade by testing that API calls no longer return stack traces with sensitive user data
  3. Alternatively or additionally, if immediate upgrade is not possible, edit php.ini and set zend.exception_ignore_args = 1, then restart the web server (PHP)
