Overview

Affected versions of this package are vulnerable to Remote Code Execution (RCE) by allowing template authors to run arbitrary PHP code using a malicious math string. If a math string was passed through as user-provided data to the math function, external users could run arbitrary PHP code by crafting a malicious math string.
