PrestaShop some attribute not escaped in Validate::isCleanHTML method
Packages
| Ecosystem | Package | Affected | Fixed in |

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