CVE-2025-10019 is an authorization bypass vulnerability found in the codepeople Contact Form Email plugin, affecting versions up to 1.3.60. The flaw arises from incorrectly configured access control security levels that allow an attacker to manipulate a user-controlled key parameter to bypass authorization checks. This vulnerability enables unauthorized actors to access or potentially modify data that should be restricted, impacting confidentiality and integrity. The CVSS 3.1 base score of 6.5 reflects a medium severity, with an attack vector of network (AV:N), low attack complexity (AC:L), no privileges required (PR:N), and no user interaction (UI:N). The scope remains unchanged (S:U), and the impact affects confidentiality and integrity partially (C:L/I:L) but not availability (A:N). Since the vulnerability can be exploited remotely without authentication or user interaction, it poses a significant risk to exposed web servers running the vulnerable plugin. No known exploits have been reported in the wild, and no official patches have been linked yet, although the vulnerability was published in December 2025. The plugin is commonly used in WordPress environments to handle contact form submissions via email, making it a critical component in many organizational websites. Attackers exploiting this flaw could gain unauthorized access to sensitive form data or manipulate form processing, potentially leading to data leakage or further compromise.

For European organizations, the impact of CVE-2025-10019 could be substantial, especially for SMEs and enterprises relying on WordPress websites with the vulnerable Contact Form Email plugin. Unauthorized access to contact form data can lead to leakage of personally identifiable information (PII), customer inquiries, or other sensitive communications, violating GDPR and other data protection regulations. Integrity compromise could allow attackers to alter form submissions or redirect communications, potentially facilitating phishing or social engineering attacks. While availability is not directly impacted, the reputational damage and regulatory penalties from data breaches could be severe. Organizations in sectors such as e-commerce, healthcare, legal services, and public administration that use this plugin for customer interaction are particularly at risk. The ease of exploitation without authentication increases the threat level, making automated scanning and exploitation feasible. The lack of known exploits in the wild currently provides a window for proactive mitigation before widespread abuse occurs.

European organizations should immediately audit their web environments to identify installations of the codepeople Contact Form Email plugin, particularly versions up to 1.3.60. Until an official patch is released, mitigation should focus on restricting access to the plugin’s endpoints via web application firewalls (WAFs) or reverse proxies, implementing strict input validation and sanitization on user-controlled keys, and disabling or limiting the plugin’s functionality if feasible. Monitoring web server logs for unusual requests targeting the plugin’s parameters can help detect exploitation attempts early. Organizations should also review access control configurations to ensure that authorization checks are correctly enforced and not bypassable via user input. Applying principle of least privilege to web server and plugin permissions reduces potential damage. Additionally, organizations should prepare to deploy patches promptly once available and consider alternative contact form solutions with stronger security postures. Employee awareness about phishing and social engineering risks stemming from compromised contact forms should be enhanced.
