XWiki's scheduler in subwiki allows scheduling operations for any main wiki user
Impact
Any user with an account on the main wiki could run scheduling operations on subwikis.
To reproduce, as a user on the main wiki without any special right, view the document Scheduler.WebHome in a subwiki. Then, click on any operation (e.g., Trigger) on any job. If the operation is successful, then the instance is vulnerable.
Patches
This has been patched in XWiki 15.10.9 and 16.3.0.
Workarounds
If you have subwikis where the Job Scheduler is enabled, you can edit the objects on Scheduler.WebPreferences to match https://github.com/xwiki/xwiki-platform/commit/54bcc5a7a2e440cc591b91eece9c13dc0c487331#diff-8e274bd0065e319a34090339de6dfe56193144d15fd71c52c1be7272254728b4.
