Description

Impact

Anyone can access the metadata of any attachment in the wiki using the wiki attachment REST endpoint. It's not filtering the result depending on current user rights, a not authenticated user could exploit this even in a totally private wiki.

To reproduce:

  • remove view from guest on the whole wiki
  • logout
  • access http://127.0.0.1:8080/xwiki/rest/wikis/xwiki/spaces/Sandbox/pages/WebHome/attachments

You get a list of attachments, while the expected result should be an empty list.
