CVE-2025-49069 is a Cross-Site Request Forgery (CSRF) vulnerability identified in the Contact Forms by Cimatti plugin, versions up to 1.9.8. CSRF vulnerabilities allow an attacker to trick an authenticated user into submitting unwanted actions on a web application in which they are currently authenticated. In this case, the vulnerability affects the Contact Forms by Cimatti, a plugin used to create and manage contact forms on websites. The vulnerability arises because the plugin does not implement adequate CSRF protections, such as anti-CSRF tokens, to validate that form submissions originate from legitimate users. An attacker could exploit this by crafting malicious web pages or links that, when visited by an authenticated user, cause the victim's browser to submit unauthorized requests to the vulnerable contact form. This could lead to unauthorized actions such as sending spam messages, injecting malicious content, or manipulating form data without the user's consent. The CVSS v3.1 base score is 4.3 (medium severity), reflecting that the attack vector is network-based, requires no privileges, but does require user interaction (the victim must visit a malicious page). The impact is limited to integrity, with no direct confidentiality or availability impact. No known exploits are currently reported in the wild, and no patches have been linked yet. The vulnerability was published on June 2, 2025, and is tracked under CWE-352, which specifically addresses CSRF issues.

For European organizations using the Contact Forms by Cimatti plugin, this vulnerability could result in unauthorized form submissions that may degrade the integrity of user-submitted data. Potential impacts include the injection of spam or malicious content into contact forms, which could damage the organization's reputation and lead to customer distrust. Additionally, attackers might exploit the vulnerability to manipulate form data, potentially causing operational disruptions or misleading communications. While the vulnerability does not directly compromise confidentiality or availability, the integrity issues could indirectly affect business processes and customer interactions. Organizations handling sensitive communications or relying heavily on web forms for customer engagement should be particularly cautious. The requirement for user interaction (victim visiting a malicious site) somewhat limits the risk but does not eliminate it, especially if phishing or social engineering campaigns are employed by attackers.

To mitigate this vulnerability, European organizations should immediately assess whether they use the Contact Forms by Cimatti plugin and identify the affected versions (up to 1.9.8). Until an official patch is released, organizations should consider the following specific actions: 1) Implement Web Application Firewall (WAF) rules to detect and block suspicious CSRF attempts targeting the contact form endpoints. 2) Restrict form submissions to POST requests with valid referrer headers and consider implementing custom CSRF tokens manually if feasible. 3) Educate users and administrators about the risks of CSRF and the importance of avoiding clicking on suspicious links or visiting untrusted websites while authenticated. 4) Monitor web server logs for unusual or repetitive form submissions that could indicate exploitation attempts. 5) Plan for prompt patching once an official fix is available from Cimatti Consulting. 6) If possible, temporarily disable the vulnerable contact forms or replace them with alternative secure contact mechanisms until the vulnerability is remediated.
