How the CVE Works:
CVE-2025-30849 exploits improper input validation in g5theme Essential Real Estate (versions ≤5.2.0), allowing attackers to manipulate file inclusion paths. The vulnerability occurs when user-supplied input is passed directly to PHP’s `include` or `require` functions without sanitization. Attackers can leverage this to include malicious local/remote files, leading to arbitrary code execution. For example, a crafted request like `https://target.com/?page=../../../malicious.php` forces the server to include unintended files. This flaw stems from weak path traversal checks and insufficient validation of dynamic file inclusion.
