The vulnerability CVE-2026-28064 in ThemeREX Edge Decor arises from improper validation or control of filenames used in PHP include or require statements. This allows an attacker to perform Local File Inclusion (LFI), which can lead to arbitrary code execution or disclosure of sensitive files on the affected system. The issue affects Edge Decor versions up to and including 2.2. The CVSS 3.1 base score is 8.1, reflecting network attack vector, high attack complexity, no privileges required, no user interaction, and high impact on confidentiality, integrity, and availability. No patch or vendor advisory is currently available, and the product is not a cloud service.

Successful exploitation of this vulnerability could allow an unauthenticated remote attacker to include and execute local files on the server running the vulnerable Edge Decor theme. This can lead to full compromise of the affected system's confidentiality, integrity, and availability. There are no known active exploits in the wild as of the published date.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance.
