### Impact Only PrestaShops with customer-thread feature flag enabled are impacted, starting from PrestaShop 8.1.0. The impact is substantial, when the customer thread feature flag is enabled, through the front-office contact form, a hacker can upload a malicious file containing an XSS that will be executed when an admin opens the attached file in back office. Consequence: the script injected can access the session and the security token, which allows it to perform any authenticated action in the scope of the administrator's right. ### Patches This vulnerability is patched in 8.1.6. ### Workarounds As long as you have not upgraded to 8.1.6, a simple workaround is to disable the customer-thread feature-flag. Thank you to Ayoub AIT ELMOKHTAR, who discovered this vulnerability and share it with the PrestaShop team.
