Server side cross-site scripting In prestashop/prestashop
Description
PrestaShop some attribute not escaped in Validate::isCleanHTML method
Description
Some event attributes are not detected by the isCleanHTML method
Impact
Some modules using the isCleanHTML method could be vulnerable to xss
Patches
8.1.3, 1.7.8.11
Workarounds
The best workaround is to use the HTMLPurifier library to sanitize html input coming from users. The library is already available as a dependency in the PrestaShop project. Beware though that in legacy object models, fields of HTML type will call isCleanHTML.
