AI-suggested

PrestaShop version 9.2.1 contains a fix for this vulnerability; administrators should upgrade affected installations to this version or later. If immediate upgrade is not possible, restrict debug mode configuration permissions to trusted administrators only and limit network access to the back office. Additionally, prevent the PHP process from having write permissions to config/defines.inc.php and config/defines_custom.inc.php where feasible, though this may impact legitimate configuration changes.

Description

PrestaShop's back-office Performance Debug mode contains a PHP code injection vulnerability. An authenticated user with permission to modify debug mode settings can inject arbitrary PHP code via crafted cookie configuration values, which are written into an executable PHP configuration file. This code executes with the privileges of the PHP process on subsequent requests. The vulnerability requires an authenticated back-office account with appropriate permissions and a writable configuration file. PrestaShop version 9.2.1 fixes this issue.
