Attack Vectors

CVE-2025-32288 is a Critical vulnerability (CVSS 9.8) affecting the RT-Theme 18 | Extensions WordPress plugin (slug: rt18-extensions) used with the RT-Theme 18 Responsive WordPress Theme, in versions 2.4 and earlier.

Because the issue is unauthenticated, an attacker does not need a login to target a vulnerable site over the internet. The vulnerability can be triggered by sending crafted requests that cause the site to include files from the server. In practical terms, this can enable data exposure and, in some scenarios, lead to running attacker-controlled code if a “safe-looking” file (such as an image or document) can be uploaded and then included.

Security Weakness

The underlying weakness is Local File Inclusion (LFI): the plugin can be manipulated into loading files it should not load. When a web application includes files based on untrusted input, it can allow attackers to pull in sensitive local files or execute code contained in included files.

This matters to business stakeholders because LFI often acts as a “gateway” issue: it can bypass access controls and expose confidential information, and in many real-world cases it can be chained with other conditions (like file upload paths) to become full remote code execution.

Technical or Business Impacts

If exploited, this Critical vulnerability can lead to outcomes that directly affect revenue, reputation, and compliance: exposure of sensitive files and data, bypassing intended restrictions, and potentially executing attacker-supplied PHP code on the server. For marketing and executive teams, that can translate into website defacement, lead-capture disruption, unauthorized redirects that harm brand trust, and downtime during incident response and restoration.

From a compliance and financial perspective, unauthorized access to customer data or internal configuration files can trigger breach notification obligations, contractual penalties, regulatory scrutiny, and unplanned spend on forensics, legal review, and PR support.

Remediation: Update RT-Theme 18 | Extensions to version 2.5 or a newer patched version as soon as possible, and prioritize this across any sites where the plugin is present (including staging or legacy marketing microsites).

Similar attacks: File inclusion and path traversal weaknesses have been used in other widely deployed platforms to expose sensitive files and enable follow-on compromise, such as CVE-2018-12613 (phpMyAdmin file inclusion) and CVE-2021-41773 (Apache HTTP Server path traversal).
