An unauthenticated attacker can make `get_page_template()` page-template resolution include a chosen readable local `.php` file outside the active theme directories. If relevant pre-conditions for both the server and the active theme are met, this can lead to RCE.
A workaround or mitigation is available. Apply it until an official patch is released.
Consider disconnecting the vulnerable system from the internet until a fix is applied.
