A vulnerability allows attackers to trick the system into loading any PHP file from the server, potentially executing malicious code. This happens because the page template function doesn't properly validate file paths.
CWE-98 (Dynamic Code Evaluation) enables unauthenticated path traversal via `get_page_template()`, allowing inclusion of arbitrary .php files outside theme directories. Exploitation requires specific server and theme configuration preconditions; successful exploitation leads to remote code execution through included PHP file execution.
In the same product, most dangerous first.
