CWE-89: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')
Reaching this weakness in Event Expresso Free <= 3.1.37.11.L takes any authenticated account. SQL injection happens when request data is concatenated into a query instead of being bound as a parameter, letting an attacker change the structure of the statement rather than just its values.
A working injection can read any table the database user can see, which on a WordPress install means user records, password hashes and session or API secrets stored in options. For Event Expresso Free the fix is 3.1.37.12.L: builds <= 3.1.37.11.L are affected, anything from 3.1.37.12.L onward is not.
Remediation
Update to version 3.1.37.12.L, or a newer patched version
