PrestaShop Performance Debug Configuration PHP Code Injection

Published Nov 9, 2026 CVSS 3.1 · 5.4 Medium EPSS < 1% KEV · Not listed
Description
PrestaShop contains an authenticated PHP code injection vulnerability in the back-office Performance debug-mode configuration. A back-office user with permission to modify debug settings can supply a crafted `debug_cookie_name` or `debug_cookie_value` that is written without sufficient escaping into a PHP configuration file. When PrestaShop subsequently loads the generated file, the injected PHP code is executed with the privileges of the web-server process.
