### Impact Any guest can perform arbitrary remote code execution through a request to `SolrSearch`. This impacts the confidentiality, integrity and availability of the whole XWiki installation. To reproduce on an instance, without being logged in, go to `<host>/xwiki/bin/get/Main/SolrSearch?media=rss&text=%7D%7D%7D%7B%7Basync%20async%3Dfalse%7D%7D%7B%7Bgroovy%7D%7Dprintln%28"Hello%20from"%20%2B%20"%20search%20text%3A"%20%2B%20%2823%20%2B%2019%29%29%7B%7B%2Fgroovy%7D%7D%7B%7B%2Fasync%7D%7D%20`. If there is an output, and the title of the RSS feed contains `Hello from search text:42`, then the instance is vulnerable. ### Patches This vulnerability has been patched in XWiki 15.10.11, 16.4.1 and 16.5.0RC1. ### Workarounds [This line](https://github.com/xwiki/xwiki-platform/blob/568447cad5172d97d6bbcfda9f6183689c2cf086/xwiki-platform-core/xwiki-platform-search/xwiki-platform-search-solr/xwiki-platform-search-solr-ui/src/main/resources/Main/SolrSearchMacros.xml#L955) in `Main.SolrSearchMa...

### Summary If there are two overlapping policies for the `update` action that allow access to different fields, instead of correctly checking access permissions against the item they apply for the user is allowed to update the superset of fields allowed by any of the policies. E.g. have one policy allowing update access to `field_a` if the `id == 1` and one policy allowing update access to `field_b` if the `id == 2`. The user with both these policies is allowed to update both `field_a` and `field_b` for the items with ids `1` and `2`. ### Details Before v11, if a user was allowed to update an item they were allowed to update the fields that the single permission, that applied to that item, listed. With overlapping permissions this isn't as clear cut anymore and the union of fields might not be the fields the user is allowed to update for that specific item. The solution that this PR introduces is to evaluate the permissions for each field that the user tries to update in the vali...
