Details
As written in the advisory (Markdown source, shown as plain text).
### 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.
