CVE-2025-23862 identifies a Missing Authorization vulnerability in the SzMake Contact Form 7 Anti Spambot plugin, affecting versions up to and including 1.0.1. The vulnerability arises from improperly configured access control security levels, which fail to enforce authorization checks on certain plugin functionalities. This misconfiguration allows unauthenticated attackers to bypass intended restrictions and interact with the plugin's features that should be protected. Since the plugin is designed to provide anti-spam capabilities for Contact Form 7, a widely used WordPress form plugin, exploitation could lead to unauthorized submission or manipulation of form data, potentially facilitating spam, data leakage, or further attacks such as injection or phishing. The vulnerability does not require user interaction or authentication, increasing its risk profile. No CVSS score is assigned yet, and no patches or known exploits have been reported as of the publication date. The issue was reserved and published in January 2025 by Patchstack. The lack of authorization checks represents a critical security flaw that undermines the plugin's purpose of securing contact forms against spam and abuse. Organizations using this plugin should consider immediate risk assessments and apply compensating controls until an official patch is available.

The impact of CVE-2025-23862 on organizations worldwide can be significant, particularly for those relying on the SzMake Contact Form 7 Anti Spambot plugin to protect their WordPress contact forms. Exploitation could allow attackers to bypass access controls, leading to unauthorized form submissions or manipulation. This can result in increased spam, phishing attempts, or injection of malicious payloads through contact forms, potentially compromising user data confidentiality and integrity. Additionally, attackers might leverage this vulnerability as a foothold for further attacks on the web server or network. The availability of the affected plugin across various WordPress sites means that many small to medium businesses, non-profits, and other organizations using Contact Form 7 with this add-on could be exposed. The absence of authentication requirements and user interaction for exploitation increases the ease of attack, potentially leading to widespread abuse. However, the impact is somewhat limited by the plugin's market penetration, which is smaller compared to more popular anti-spam solutions. Nonetheless, the vulnerability poses a direct threat to the confidentiality and integrity of form data and could degrade trust in affected websites.

To mitigate CVE-2025-23862, organizations should immediately audit their WordPress installations to identify the presence of the SzMake Contact Form 7 Anti Spambot plugin, especially versions up to 1.0.1. Until an official patch is released, administrators should restrict access to the plugin’s endpoints by implementing web application firewall (WAF) rules that block unauthorized requests targeting the plugin’s functionalities. Disabling or uninstalling the plugin temporarily can prevent exploitation if the anti-spam functionality is not critical or can be replaced with alternative solutions. Monitoring web server logs for unusual or unauthorized access attempts to the plugin’s URLs can help detect exploitation attempts early. Additionally, organizations should ensure that WordPress and all plugins are kept up to date and subscribe to security advisories from the plugin vendor or trusted vulnerability databases. Implementing multi-layered spam protection strategies, such as CAPTCHA or other anti-spam plugins with robust authorization controls, can reduce reliance on vulnerable components. Finally, preparing an incident response plan for potential exploitation scenarios will improve readiness.
