CVE-2026-124916 · Severity: info · Published 2026-11-09

PrestaShop is an e-commerce platform that allows merchants to build and manage online stores. An authenticated employee with Performance permissions can inject malicious PHP code through debug settings that executes with web server privileges on every request, potentially compromising the entire store's front and back office. This is a privilege escalation, as such employees normally cannot execute arbitrary code or modify other administrator accounts.

## Technical details

The vulnerability is a code injection flaw (CWE-94) in PrestaShop's back-office Performance debug-mode configuration. An authenticated back-office user with Performance permissions can inject PHP code via the `debug_cookie_name` or `debug_cookie_value` fields, which are written unsanitized into a PHP configuration file loaded on every request. The injected code executes with web server privileges, enabling remote code execution and privilege escalation for low-privilege administrative accounts.
