Technical details
A Local File Inclusion (LFI) vulnerability exists in the ThemeREX Gunslinger theme for WordPress through version 1.7. The flaw stems from improper control of filenames in PHP include/require statements (CWE-98), allowing an unauthenticated remote attacker to include arbitrary local files via specially crafted requests.

As of the advisory date, no official patch has been released.
