CVE-2026-62133 Overview
CVE-2026-62133 is a Cross-Site Request Forgery (CSRF) vulnerability [CWE-352] affecting the RTMKit (Rometheme for Elementor) WordPress plugin in versions up to and including 2.1.5. The flaw allows an attacker to trick an authenticated subscriber into submitting unintended state-changing requests to a vulnerable WordPress site. Exploitation requires user interaction, typically through a crafted link or malicious page visited while the victim is logged in. Successful exploitation can lead to limited integrity and availability impact on the target site.
Critical Impact
Attackers can abuse an authenticated subscriber's session to perform unauthorized actions in RTMKit, resulting in limited data modification and service disruption.
Affected Products
- RTMKit (Rometheme for Elementor) WordPress plugin, versions <= 2.1.5
- WordPress sites with the affected plugin installed and active
- Any site allowing subscriber-level user registration alongside the affected plugin

Technical Details for CVE-2026-62133
Vulnerability Analysis
The vulnerability stems from missing or improperly validated anti-CSRF protections on state-changing actions exposed by the RTMKit plugin. When a subscriber-level user is authenticated on the target WordPress site, an attacker-controlled page can issue forged requests that the plugin processes as legitimate. Because the request originates from the victim's browser, it inherits the victim's session cookies and permissions.
CSRF vulnerabilities in WordPress plugins typically occur when developers omit nonce validation via wp_verify_nonce() or check_admin_referer() on handlers that modify server-side state. Without these checks, the plugin cannot distinguish between a request initiated by the user and one forged by an external site.
The scope of impact is bounded by subscriber privileges. Confidentiality is not affected, but limited integrity and availability degradation can occur on plugin-managed data or configuration.
Root Cause
The root cause is a missing CSRF token verification step on one or more request handlers in RTMKit <= 2.1.5. The plugin trusts the presence of an authenticated session without confirming that the request originated from a trusted UI flow.
Attack Vector
Exploitation requires the following conditions: the victim must hold an active subscriber (or higher) session on the WordPress target, and the victim must visit an attacker-controlled page or click a malicious link. The attacker page issues a cross-origin request (via an HTML form auto-submit or image tag) to the vulnerable RTMKit endpoint. The victim's browser attaches the WordPress session cookie, and the plugin processes the forged action.

Detection Methods for CVE-2026-62133
Indicators of Compromise
- Unexpected changes to RTMKit plugin settings or content items without corresponding admin console activity
- HTTP POST requests to RTMKit endpoints with Referer headers pointing to external, untrusted domains
- Subscriber-account activity that produces state changes outside normal user workflows
Detection Strategies
- Inspect web server access logs for requests to RTMKit plugin endpoints originating from cross-origin Referer values
- Correlate WordPress audit-log entries with authenticated subscriber sessions to identify anomalous state-changing actions
- Deploy a WordPress security plugin that logs nonce validation failures and plugin-level configuration changes
Monitoring Recommendations
- Enable verbose logging on the WordPress site and forward events to a centralized SIEM for correlation
- Alert on repeated requests to the same RTMKit endpoint from multiple subscriber accounts within a short window
- Track new subscriber registrations followed by state-changing plugin requests within a single session
How to Mitigate CVE-2026-62133
Immediate Actions Required
- Update the RTMKit (Rometheme for Elementor) plugin to a version later than 2.1.5 once a patched release is available
- Audit subscriber-level accounts and remove any that are unused or unrecognized
- Review recent plugin activity logs for evidence of unauthorized state changes
Patch Information
Refer to the Patchstack CSRF Vulnerability Report for current patch availability and vendor guidance. Upgrade to the fixed release as soon as it is published by the plugin author.
Workarounds
- Temporarily disable the RTMKit plugin until a patched version is installed
- Disable open user registration or restrict registration to trusted email domains to reduce the attacker's ability to obtain subscriber sessions
- Deploy a Web Application Firewall (WAF) rule that enforces Origin and Referer header validation on RTMKit plugin endpoints
- Instruct administrators and privileged users to log out of the WordPress dashboard when not actively using it
