CVE-2024-13555 in 1 Click Migration Plugin
Summary
by MITRE • 02/18/2025
The 1 Click WordPress Migration Plugin – 100% FREE for a limited time plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 2.1. This is due to missing or incorrect nonce validation on the cancel_actions() function. This makes it possible for unauthenticated attackers to cancel a triggered backup via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.

The CVE-2024-13555 vulnerability affects the 1 Click WordPress Migration Plugin, a widely used tool for WordPress site migrations that offers free functionality for a limited time period. This plugin serves as a critical component in the WordPress ecosystem, enabling users to transfer their entire website including content, themes, plugins, and settings from one location to another. The vulnerability resides within the plugin's security mechanisms, specifically targeting its handling of cross-site request forgery protection measures. The issue impacts all versions of the plugin up to and including version 2.1, representing a significant security risk for WordPress administrators who rely on this migration tool for their site management operations.
The technical flaw manifests in the cancel_actions() function which lacks proper nonce validation, a fundamental security mechanism designed to prevent unauthorized requests from being executed on behalf of authenticated users. Nonces, or number used once, are cryptographic tokens that verify the authenticity of requests and ensure that actions are performed by legitimate users with proper authorization. In this case, the absence of correct nonce validation creates a pathway for attackers to manipulate the plugin's functionality without requiring authentication. The vulnerability operates under the principle that if an attacker can successfully trick a logged-in administrator into performing a malicious action, they can leverage this to execute unauthorized operations within the plugin's scope.
The operational impact of this vulnerability extends beyond simple privilege escalation, as it allows unauthenticated attackers to perform critical administrative functions within the WordPress environment. When an administrator clicks on a malicious link or visits a compromised webpage, the forged request can trigger the cancellation of backup operations that are typically initiated through legitimate administrative workflows. This represents a serious concern for WordPress site owners since backup operations are essential for disaster recovery and data protection. An attacker could potentially disrupt backup schedules, cause data loss, or manipulate the migration process to compromise the integrity of the website's data and configuration. The vulnerability essentially allows attackers to execute arbitrary actions within the plugin's administrative interface without possessing valid credentials.
This vulnerability aligns with CWE-352, which specifically addresses Cross-Site Request Forgery (CSRF) weaknesses in software applications. The issue demonstrates poor input validation and insufficient security controls that violate fundamental web application security principles. From an ATT&CK framework perspective, this vulnerability maps to techniques involving privilege escalation and execution of malicious commands through social engineering approaches. The attack vector relies heavily on user interaction, making it particularly dangerous in environments where administrators frequently visit external websites or receive suspicious links via email or other communication channels. The vulnerability also represents a failure in the principle of least privilege, as the plugin does not properly validate the authenticity of requests before executing sensitive operations. Organizations should immediately implement mitigation strategies including updating to patched versions of the plugin, implementing additional security layers such as web application firewalls, and educating administrators about the risks of clicking untrusted links. Regular security audits and monitoring of plugin installations are essential to prevent exploitation of similar vulnerabilities in other WordPress components.
