CWE-89: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')

Reaching this weakness in The Plus Addons for Elementor Page Builder Pro < 5.0.7 takes a caller who can reach the endpoint. 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 The Plus Addons for Elementor Page Builder Pro the fix is 5.0.7: builds < 5.0.7 are affected, anything from 5.0.7 onward is not.

Remediation

Update to version 5.0.7, or a newer patched version
