Technical Details
Vulnerability Mechanism & Technical Analysis
This vulnerability is classified under CWE-472: External Control of Assumed-Immutable Web Parameter, where the web application does not sufficiently verify inputs that are assumed to be immutable but are actually externally controllable, such as hidden form fields. In Moodle/moodle, software state validation or input boundaries are circumvented during processing.
