CVE-2025-29000 is a high-severity vulnerability classified under CWE-862 (Missing Authorization) affecting the August Infotech Multi-language Responsive Contact Form, versions up to 2.8. This vulnerability arises because the application fails to properly enforce Access Control Lists (ACLs) on certain functionality, allowing unauthorized users to access features or operations that should be restricted. The CVSS 3.1 base score is 7.5, reflecting a network exploitable vulnerability (AV:N) with low attack complexity (AC:L), requiring no privileges (PR:N) and no user interaction (UI:N). The scope is unchanged (S:U), and the impact is high on confidentiality (C:H) but no impact on integrity (I:N) or availability (A:N). This means an attacker can remotely access sensitive information or functionality without authentication or user interaction, potentially leading to data exposure or unauthorized access to protected resources. The vulnerability affects the Multi-language Responsive Contact Form plugin, which is commonly used to provide contact form functionality on websites, often integrated into CMS platforms or custom web applications. Since the vulnerability is related to missing authorization, it likely allows attackers to bypass intended access restrictions, possibly retrieving sensitive data submitted via the form or accessing administrative functions. No patches or fixes are currently linked, and no known exploits have been reported in the wild as of the publication date (July 16, 2025). However, the ease of exploitation and high confidentiality impact make this a significant risk for organizations using this product.

For European organizations, this vulnerability poses a substantial risk, especially for those relying on the August Infotech Multi-language Responsive Contact Form for customer interaction or data collection. Unauthorized access to sensitive form data could lead to exposure of personal data, potentially violating GDPR and other data protection regulations, resulting in legal and financial penalties. The confidentiality breach could undermine customer trust and damage brand reputation. Additionally, attackers might leverage this vulnerability as an initial foothold to gather intelligence or pivot to other internal systems if the contact form is integrated with backend services. The lack of required authentication and user interaction means attacks can be automated and executed at scale, increasing the threat surface. Organizations in sectors such as finance, healthcare, e-commerce, and government, which handle sensitive personal or financial data, are particularly at risk. Furthermore, since the vulnerability affects a multi-language form, it is likely deployed in multinational environments, increasing the scope of potential impact across European countries.

Given the absence of an official patch, European organizations should immediately conduct an inventory to identify all instances of the August Infotech Multi-language Responsive Contact Form in use. As a temporary mitigation, restrict access to the contact form functionality via network-level controls such as web application firewalls (WAFs) or reverse proxies configured with strict ACLs to limit access to trusted IP ranges or authenticated users only. Implement monitoring and alerting for unusual access patterns or data exfiltration attempts targeting the contact form endpoints. Review and harden server-side authorization logic where possible, applying custom access controls to sensitive functions. If feasible, disable or remove the vulnerable contact form plugin until a patch is available. Organizations should also ensure that all data collected via the form is encrypted at rest and in transit, minimizing exposure in case of unauthorized access. Finally, maintain close communication with August Infotech for updates on patches or official remediation guidance and plan for prompt deployment once available.
