CVE-2025-53304 is a medium severity vulnerability classified under CWE-862 (Missing Authorization) affecting the Rohil Contact Form – 7 : Hide Success Message plugin, versions up to 1.1.4. This vulnerability arises due to improper access control mechanisms, allowing unauthorized users to access functionality that should be restricted by Access Control Lists (ACLs). Specifically, the flaw permits an attacker to invoke certain functions within the plugin without proper authorization checks, potentially leading to unauthorized actions that impact the integrity of the system. The vulnerability is remotely exploitable over the network without requiring any privileges or user interaction, as indicated by the CVSS vector (AV:N/AC:L/PR:N/UI:N). While the vulnerability does not directly compromise confidentiality or availability, it allows unauthorized modification or manipulation of plugin behavior or data, thus impacting integrity. No known exploits are currently reported in the wild, and no patches have been linked yet. The plugin is typically used in WordPress environments to manage contact forms and customize success message behavior, making it a common component in many websites. The missing authorization check could be leveraged by attackers to bypass intended restrictions, potentially enabling unauthorized form submissions or manipulation of success message displays, which might be used as a vector for further attacks such as social engineering or phishing campaigns.

For European organizations, the impact of this vulnerability depends largely on the extent to which the Rohil Contact Form – 7 : Hide Success Message plugin is deployed within their web infrastructure. Organizations relying on this plugin for customer interaction or lead generation could face integrity issues where unauthorized actors manipulate form responses or success messages, potentially misleading users or disrupting business workflows. Although the vulnerability does not directly expose sensitive data, the ability to alter form behavior without authorization could be exploited to inject misleading information or facilitate phishing attacks, undermining user trust and brand reputation. Additionally, unauthorized access to form functionality could be chained with other vulnerabilities to escalate attacks. Given the widespread use of WordPress in Europe, especially among SMEs and public sector websites, the risk of exploitation could affect sectors such as e-commerce, government services, and education. The lack of authentication and user interaction requirements lowers the barrier for exploitation, increasing the risk of automated attacks targeting vulnerable sites.

To mitigate this vulnerability, European organizations should first inventory their WordPress installations to identify the presence of the Rohil Contact Form – 7 : Hide Success Message plugin. Until an official patch is released, organizations should consider disabling or uninstalling the plugin if it is not critical to operations. For sites where the plugin is essential, implementing web application firewall (WAF) rules to restrict access to the vulnerable functionality can help reduce exposure. Monitoring web server logs for unusual or unauthorized access patterns related to the plugin’s endpoints is recommended. Additionally, organizations should enforce strict role-based access controls within WordPress to limit administrative privileges and reduce the risk of exploitation. Regularly updating all WordPress plugins and themes, and subscribing to vulnerability advisories related to Rohil products, will ensure timely application of patches once available. Finally, educating web administrators about this vulnerability and encouraging prompt response to security notices will enhance overall resilience.
