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

Reaching this weakness in Slider Hero with Video Background, Animation < 8.2.7 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 Slider Hero with Video Background, Animation the fix is 8.2.7: builds < 8.2.7 are affected, anything from 8.2.7 onward is not.

Remediation

Update to version 8.2.7, or a newer patched version
