PHP Injection vulnerability in the module "M4 PDF Extensions" (m4pdf) up to version 3.3.2 from PrestaAddons for PrestaShop allows attackers to run arbitrary code via the M4PDF::saveTemplate() method.
The product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment.
