CVE-2025-14173 is a vulnerability classified under CWE-862 (Missing Authorization) affecting the Perfit WooCommerce plugin for WordPress, specifically all versions up to and including 1.0.1. The root cause is the absence of proper authorization checks in the plugin's logout function, which is invoked via the actions function hooked to the WordPress admin_init action. This flaw allows unauthenticated attackers to invoke the logout function by manipulating the action parameter in HTTP requests, leading to the deletion of arbitrary plugin settings. Since the logout function is accessible without verifying the user's permissions, attackers can remotely exploit this vulnerability without any credentials or user interaction. The vulnerability impacts the integrity of the plugin's configuration by enabling unauthorized deletion of settings, potentially disrupting e-commerce operations or causing misconfigurations. The CVSS v3.1 base score is 5.3, indicating medium severity, with vector AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N, meaning the attack is network-based, requires low attack complexity, no privileges, no user interaction, and affects only integrity without confidentiality or availability impact. There are no known public exploits or patches available at the time of publication, increasing the urgency for organizations to apply compensating controls. The vulnerability was reserved in December 2025 and published in January 2026 by Wordfence.

The primary impact of CVE-2025-14173 is the unauthorized modification of plugin settings, which compromises the integrity of the Perfit WooCommerce plugin configuration. This can lead to operational disruptions in e-commerce workflows, such as disabling critical features, altering pricing or payment settings, or corrupting plugin behavior. Although confidentiality and availability are not directly affected, the integrity loss can indirectly cause business interruptions or loss of customer trust. Since the vulnerability can be exploited remotely without authentication, attackers can target any vulnerable WordPress site running the affected plugin, increasing the attack surface significantly. Organizations relying on Perfit WooCommerce for their online stores may face increased risk of configuration tampering, potentially leading to financial losses or reputational damage. The lack of known exploits reduces immediate risk, but the ease of exploitation and absence of patches elevate the threat level for unpatched systems.

To mitigate CVE-2025-14173, organizations should immediately audit their WordPress installations to identify the presence of the Perfit WooCommerce plugin and its version. Until an official patch is released, administrators should implement the following specific measures: 1) Restrict access to the WordPress admin_init hook by applying web application firewall (WAF) rules that block unauthorized requests containing suspicious action parameters targeting the logout function. 2) Employ strict IP whitelisting or VPN access for administrative interfaces to limit exposure to trusted users only. 3) Monitor web server and application logs for unusual requests with the action parameter manipulating plugin settings, enabling early detection of exploitation attempts. 4) Disable or remove the Perfit WooCommerce plugin if it is not essential, or replace it with a more secure alternative. 5) Engage with the plugin vendor for updates and patches and apply them promptly once available. 6) Harden WordPress security by enforcing least privilege principles on user roles and regularly reviewing plugin permissions. These targeted steps go beyond generic advice by focusing on access control, monitoring, and immediate risk reduction in the absence of a patch.
