Detailsinfo

A vulnerability was found in PrestaShop up to 9.2.0. It has been rated as problematic. Affected by this issue is an unknown function of the component Performance debug-mode configuration. The manipulation of the argument debug_cookie_name/debug_cookie_value with an unknown input leads to a code injection vulnerability. Using CWE to declare the problem leads to CWE-94.
