Description

### Impact This is a **stored Cross-site Scripting (XSS)** vulnerability in the PrestaShop back-office Customer Service view. An unauthenticated attacker can submit the public Contact Us form with a malicious email address. The payload is stored in the database and executed when a back-office employee opens the affected customer thread, enabling session hijacking and full back-office takeover. ### Patches Patched in PrestaShop 8.2.6 and 9.1.1. ### Workarounds None. ### Resources - Reported by Savio at Doyensec (`anthropic@doyensec.com`) in collaboration with Anthropic Research.
