Miggo AIMiggo AIMiggo AIRoot Cause AnalysisThe vulnerability stems from unsafe use of PHP's native unserialize() function on user-controlled input. The patch replaces all instances of unserialize() with a custom unserialize_object() function, which mitigates the risk by enforcing stricter deserialization controls (likely via the safe_unserialize() pattern). CWE-94 explicitly identifies code injection via unserialization as the weakness. The affected code paths handle lesson activity data (user answers, conditions), which teachers/managers could manipulate to trigger the exploit.
