Directory /var/www/html/vendor/ezyang/htmlpurifier/library/HTMLPurifier/DefinitionCache/Serializer not writable.

Why does this library need the vendor folder on which it lives to be writeable?

It seems unnecessary, and it opens the possibility of vulnerabilities.

I have the same problem. How to solve?

@jpruiz114 You can change the default folder path using a property, e.g.

$serializerPath = '/tmp/htmlpurifier';
if (!file_exists($serializerPath)) {
mkdir($serializerPath);
}
$config->set('Cache.SerializerPath', $serializerPath);
