CVE-2025-46554: XWiki missing authorization when accessing the wiki level attachments list and metadata via REST API
(updated )
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.
