Other vulnerabilities in RTMKit
See all- CVE-2026-62133Medium
The RTMKit plugin in versions up to and including 2.1.5 is vulnerable to Cross Site Request Forgery (CSRF). A user with the Subscriber role can be tricked into performing unwanted actions.
- CVE-2026-84763High
Unauthenticated Cross Site Scripting (XSS) in RTMKit versions up to 2.1.5. An attacker can inject malicious script without authentication.
- CVE-2026-12907Low
The RTMKit WordPress plugin before version 2.0.9 fails to perform a proper capability check on one of its builder AJAX actions. Users with at least the Author role can create and activate a site-wide template that overrides the header, footer, or other global areas displayed to all visitors, which is normally restricted to administrators.
- CVE-2026-12906Low
The RTMKit WordPress plugin before version 2.0.9 fails to perform a capability check in one of its AJAX actions and directly resolves a request-supplied post identifier, allowing users with at least the Contributor role to read the titles of other users' private, draft, pending, scheduled, and trashed posts.
- CVE-2026-5137Medium
The RTMKit (rometheme-for-elementor) plugin for WordPress up to version 2.0.7 is vulnerable to Local File Inclusion (LFI). This is due to insufficient path validation on the 'template' parameter in the render_templates AJAX endpoint, which is used directly in a require/include statement without sanitization. This allows authenticated attackers with Contributor-level access and above to include and execute files on the server ending in _templates.php, enabling the execution of any PHP code in those files.
- CVE-2026-8351Medium
The RTMKit plugin for WordPress up to version 2.0.7 contains a stored XSS vulnerability in the Advanced Heading widget. It stems from insufficient output escaping of the 'Background Text' parameter in the render() function, allowing authenticated attackers with contributor-level access or higher to inject arbitrary scripts.
