CVE-2025-12473

RTMKit <= 1.6.8 - Reflected Cross-Site Scripting via 'themebuilder' Parameter

Published Mar 11, 2026 CVSS 3.1 · 6.1 Medium EPSS < 1% KEV · Not listed

Description

The RTMKit plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'themebuilder' parameter in all versions up to, and including, 1.6.8 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a site administrator into performing an action such as clicking on a link.

Analysis

Technical impact

The RTMKit WordPress plugin contains a Reflected Cross‑Site Scripting flaw that is triggered by sending the "themebuilder" parameter in any request. The vulnerability arises from insufficient input sanitization and output escaping, which allows an unauthenticated attacker to embed arbitrary JavaScript. If a site administrator inadvertently visits a crafted URL or clicks a malicious link, the malicious script will run in the administrator’s browser and could be used to modify page content or compromise the session.

Affected Systems

All releases of the RTMKit plugin provided by rometheme that are version 1.6.8 or older are affected, as indicated by the vendor’s code repository references.

Risk and Exploitability

The CVSS score of 6.1 indicates moderate severity. The EPSS score is reported as less than 1 %, suggesting a low likelihood of immediate exploitation, and the vulnerability is not listed in the CISA KEV catalog. Based on the description, it is inferred that the attack vector is unauthenticated, remote, web‑based exploitation that requires delivering a crafted request containing a malicious value for the "themebuilder" parameter to an administrator’s browser.

OpenCVE Recommended Actions

Check if a newer RTMKit version (e.g., 2.0.0) is available that removes the vulnerability and upgrade if feasible.
If an update cannot be applied promptly, disable or remove the themebuilder functionality or uninstall the RTMKit plugin entirely.
After applying a fix or disabling the feature, test the site to confirm that requests containing the "themebuilder" parameter no longer produce reflected XSS.
