Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-200: Exposure of Sensitive Information to an Unauthorized Actor, where the product exposes sensitive information to an actor that is not explicitly authorized to have access to that information. In Moodle/moodle, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

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 where PHP is configured with zend.exception_ignore_args = 'On' or zend.exception_ignore_args = 1 in the relevant php.ini file are NOT affected by this vulnerability. Sites that do not have the zend.exception_ignore_args setting enabled and are using the internal Moodle LMS authentication system are affected by this vulnerability.
