CWE-89: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')
Reaching this weakness in Speed Booster Pack ⚡ PageSpeed Optimization Suite <= 4.3.3 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 Speed Booster Pack ⚡ PageSpeed Optimization Suite the fix is 4.3.3.1: builds <= 4.3.3 are affected, anything from 4.3.3.1 onward is not.
Remediation
Update to version 4.3.3.1, or a newer patched version
