CVE-2025-64283: RTMKit Authorization Bypass Vulnerability

CVE-2025-64283 Overview

CVE-2025-64283 is an Insecure Direct Object Reference (IDOR) vulnerability in the Rometheme RTMKit (rometheme-for-elementor) WordPress plugin. The flaw is classified as Authorization Bypass Through User-Controlled Key [CWE-639] and affects all plugin versions up to and including 1.6.7. An authenticated attacker with low privileges can manipulate user-controlled identifiers to access resources belonging to other users. The vulnerability results from incorrectly configured access control checks on object references exposed through the plugin.

Critical Impact
Authenticated attackers can bypass authorization checks and read confidential data belonging to other users by tampering with object identifiers in plugin requests.

Affected Products

Rometheme RTMKit (rometheme-for-elementor) plugin versions through 1.6.7
WordPress sites running the RTMKit plugin as an Elementor add-on
Environments allowing subscriber-level or higher authenticated access

Technical Details for CVE-2025-64283

Vulnerability Analysis

The vulnerability is an Insecure Direct Object Reference in the RTMKit plugin for Elementor. The plugin accepts identifiers supplied by the client and returns or acts on the corresponding object without verifying that the requesting user is authorized for that specific object. This pattern breaks horizontal access control between users of the same privilege tier. According to the vendor advisory published through Patchstack, the issue affects all versions up to and including 1.6.7.

An attacker needs only an authenticated session at a low privilege level to abuse the flaw. No user interaction is required, and the attack is delivered over the network. Confidentiality of data managed by the plugin is at risk, while integrity and availability are not directly impacted by this specific issue.

Root Cause

The root cause is missing or insufficient authorization enforcement on object identifiers passed in plugin requests. The application trusts a user-controlled key, such as a numeric record ID, and fetches the corresponding record without validating ownership. This is the canonical [CWE-639] pattern: authorization decisions rely on data supplied by the caller rather than on server-side session context.

Attack Vector

Exploitation is performed over the network by an authenticated user. The attacker submits a request to a plugin endpoint and substitutes a target object identifier belonging to another user. Because the plugin does not verify that the session owner is authorized for the requested object, the server returns the requested data. Iterating identifiers enables bulk enumeration of records across tenants or users. See the Patchstack Vulnerability Report for additional technical detail.

Detection Methods for CVE-2025-64283

Indicators of Compromise

Sequential or scripted access patterns to RTMKit endpoints containing incrementing numeric identifiers in query strings or POST bodies
Authenticated sessions from low-privilege accounts retrieving records associated with different user IDs
Unusual volumes of HTTP 200 responses from rometheme-for-elementor endpoints tied to a single session

Detection Strategies

Review WordPress and web server access logs for repeated requests to RTMKit plugin routes with varied id parameters
Correlate authenticated user IDs with the object IDs returned by the plugin to flag cross-user access
Alert on subscriber or contributor accounts making high-frequency requests to plugin AJAX endpoints

Monitoring Recommendations

Enable verbose access logging on WordPress endpoints exposed by RTMKit and forward logs to a central analytics platform
Track baseline request rates per authenticated user and alert on deviations targeting plugin routes
Monitor for privilege-tier anomalies where low-privilege users retrieve data typically accessed by administrators or editors

How to Mitigate CVE-2025-64283

Immediate Actions Required

Identify all WordPress instances running the Rometheme RTMKit rometheme-for-elementor plugin at version 1.6.7 or earlier
Restrict access to plugin endpoints at the web application firewall until a patched version is applied
Audit recent access logs for suspicious patterns consistent with IDOR enumeration

Patch Information

At the time of NVD publication, a fixed version had not been recorded in the advisory. Consult the Patchstack Vulnerability Report for the latest fix status and upgrade to the first version released after 1.6.7 that addresses the issue.

Workarounds

Disable or remove the RTMKit plugin until an upgrade is available if the affected functionality is not business critical
Limit account registration and restrict subscriber-level accounts on sites that expose the plugin
Deploy a WAF rule that blocks unauthenticated or low-privilege requests to RTMKit endpoints referencing arbitrary object IDs

bash

# Example WAF rule concept: block low-privilege access to RTMKit object endpoints
# Adapt for ModSecurity, Cloudflare, or equivalent
SecRule REQUEST_URI "@contains /wp-content/plugins/rometheme-for-elementor/" \
  "id:1006428,phase:2,deny,status:403,\
   msg:'Blocked RTMKit IDOR CVE-2025-64283 probe',\
   chain"
  SecRule ARGS:id "@rx ^[0-9]+$"
