Path Traversal

TL;DR

get_page_template() resolves a page template from attacker-influenced input without confining the resulting path to the active theme directories. An unauthenticated request can therefore cause WordPress to include a chosen readable local .php file outside the theme. When the active child or parent theme has a top-level directory whose name starts with page- (for example page-templates) and a suitable local PHP file is readable by the web server, that include becomes remote code execution. The fix restricts page-template resolution so paths cannot escape the theme directories.

How do I fix this?

Upgrade the roots/wordpress library to the patch version.

Who does this affect?

You are affected if you are using a version that falls within the vulnerable range and the active child or parent theme contains a top-level directory whose name starts with page-. Reaching code execution also requires a readable local .php file on the server (for example pearcmd.php when register_argc_argv is On).
