CVE-2025-12825 is a vulnerability categorized under CWE-862 (Missing Authorization) affecting the 'User Registration Using Contact Form 7' WordPress plugin developed by zealopensource. The vulnerability exists because the function 'get_cf7_form_data', responsible for retrieving form configuration data, lacks proper capability checks to verify if the requesting user is authorized to access this information. As a result, unauthenticated attackers can remotely invoke this function to obtain sensitive form settings, including Facebook app secrets embedded within the configuration. These secrets could potentially be used to impersonate the application or escalate attacks against integrated Facebook services. The vulnerability affects all plugin versions up to and including 2.5. The attack vector is network-based with no authentication or user interaction required, making it relatively easy to exploit. However, the impact is limited to confidentiality as the vulnerability does not allow modification of data or disruption of service. No public exploits have been reported yet, but the exposure of OAuth credentials or app secrets can have downstream security implications. The CVSS v3.1 base score is 5.3, reflecting a medium severity rating due to the ease of exploitation but limited scope of impact.

The primary impact of CVE-2025-12825 is the unauthorized disclosure of sensitive configuration data, specifically Facebook app secrets, from WordPress sites using the affected plugin. This leakage can compromise the confidentiality of OAuth credentials, potentially enabling attackers to impersonate the application in Facebook integrations or perform further attacks such as token theft, unauthorized API calls, or social engineering campaigns. While the vulnerability does not allow direct modification of data or denial of service, the exposure of secrets can lead to indirect compromise of user accounts or data privacy breaches. Organizations relying on Facebook integrations via this plugin may face reputational damage, regulatory compliance issues, and increased risk of targeted attacks. The vulnerability's ease of exploitation without authentication increases the risk surface, especially for publicly accessible WordPress sites. However, the absence of known exploits in the wild suggests limited active exploitation at present, though this could change once details become widely known.

To mitigate CVE-2025-12825, organizations should immediately update the 'User Registration Using Contact Form 7' plugin to a patched version once available from zealopensource. In the absence of an official patch, administrators should implement strict access controls to restrict access to the vulnerable function, such as limiting access to authenticated and authorized users only. Employing Web Application Firewalls (WAFs) with custom rules to block unauthorized requests targeting the 'get_cf7_form_data' endpoint can reduce exposure. Additionally, review and rotate any exposed Facebook app secrets or OAuth credentials to prevent misuse. Monitoring web server logs for suspicious access patterns to the vulnerable function can help detect exploitation attempts. It is also advisable to audit other plugins and integrations for similar missing authorization issues. Finally, educating site administrators about the risks of exposing sensitive configuration data and enforcing the principle of least privilege in plugin capabilities will help prevent similar vulnerabilities.
