13.10.4- Upgrade org.xwiki.platform:xwiki-platform-oldcore to this version or later
Description
Impact
All rights checks that would normally prevent a user from viewing a document on a wiki can be bypassed using the login action and directly specified templates. This exposes title, content and comments of any document and properties of objects (class and property name must be known, though). This is also exploitable on private wikis.
Patches
This has been patched in versions 14.2 and 13.10.4 by properly checking view rights before loading documents and disallowing non-default templates in the login, registration and skin action.
Workarounds
It would be possible to protect all templates individually by adding code to check access rights first, but due to the number of templates and the fact that some of them need to be used without view rights, this seems impractical.

How to fix
Move to the fixed version or later with your package manager, update the lockfile, and run your tests. If the package only arrives through another dependency, upgrade that dependency first. If none of its releases pulls a fixed version yet, force the version with your package manager's override.
