CVE-2022-31181Known exploitationNetwork attack vector

Remote code execution via unencrypted Smarty cache

Published Aug 1, 2022 · Updated Apr 23, 2025

Eval injection in PrestaShop 1.6.0.10 through 1.7.8.6 allows remote attackers to execute arbitrary PHP code after SQL injection. The MySQL Smarty cache fetches database-controlled template content without decrypting or authenticating it, allowing injected cache rows to reach dynamic evaluation. Exploitation requires MySQL Smarty caching and a separate SQL injection, after which attackers can control the shop and steal payment data.
