CVE-2025-47456 is a medium-severity vulnerability classified under CWE-601, which corresponds to an 'Open Redirect' issue found in the CRM Perks WP Gravity Forms Zendesk plugin. This vulnerability affects versions up to 1.1.2 of the plugin. An open redirect vulnerability occurs when a web application accepts a user-controlled input that specifies a link to an external site and redirects the user to that site without proper validation. In this case, the WP Gravity Forms Zendesk plugin improperly handles URL redirection parameters, allowing attackers to craft malicious URLs that redirect users to untrusted, potentially malicious websites. This behavior can be exploited primarily for phishing attacks, where users are tricked into believing they are navigating to a legitimate site but are instead redirected to a fraudulent one designed to steal credentials or deliver malware. The CVSS 3.1 base score of 4.7 reflects a medium severity level, with the vector indicating network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:N), user interaction required (UI:R), scope changed (S:C), and limited confidentiality impact (C:L) but no integrity or availability impact. The scope change indicates that the vulnerability affects components beyond the vulnerable plugin itself, potentially impacting the broader system or user session. No known exploits are currently reported in the wild, and no patches have been linked yet, suggesting that the vulnerability is newly disclosed and may require immediate attention from administrators using this plugin. The vulnerability is particularly relevant for websites using WordPress with the CRM Perks WP Gravity Forms Zendesk integration, which is commonly used to connect Gravity Forms submissions to Zendesk ticketing systems. Attackers leveraging this vulnerability can craft URLs that, when clicked by users, redirect them to malicious sites, facilitating phishing campaigns or other social engineering attacks.

For European organizations, the impact of this vulnerability can be significant, especially for those relying on WordPress-based customer relationship management (CRM) and support systems that integrate Gravity Forms with Zendesk via the CRM Perks plugin. Successful exploitation could lead to phishing attacks targeting employees, customers, or partners, potentially resulting in credential theft, unauthorized access, or reputational damage. Given the widespread use of WordPress and Zendesk in Europe, particularly among small to medium enterprises and customer support centers, this vulnerability could be leveraged to undermine trust in digital services. The confidentiality impact is limited to the potential exposure of user credentials or sensitive information through phishing, but there is no direct compromise of data integrity or availability. However, the indirect consequences, such as account takeover or fraud resulting from stolen credentials, could escalate the overall impact. Additionally, the requirement for user interaction means that social engineering tactics will be necessary, which are often effective in targeted attacks. The vulnerability could also be exploited in supply chain attacks if attackers target service providers or agencies managing multiple client websites using this plugin. Organizations in sectors with high customer interaction, such as finance, healthcare, and e-commerce, may face elevated risks due to the potential for phishing campaigns leveraging this vulnerability.

To mitigate this vulnerability, European organizations should take the following specific actions: 1) Immediately audit all WordPress installations to identify the presence of the CRM Perks WP Gravity Forms Zendesk plugin and confirm the version in use. 2) Monitor official vendor channels and security advisories for the release of patches or updates addressing CVE-2025-47456 and apply them promptly once available. 3) Implement strict input validation and URL whitelisting on redirect parameters within the plugin or via custom code to prevent open redirects. 4) Employ web application firewalls (WAFs) with rules designed to detect and block suspicious redirect patterns or known phishing URLs. 5) Educate users and staff about the risks of phishing, emphasizing caution when clicking on links, especially those received via email or external sources. 6) Use multi-factor authentication (MFA) on critical systems to reduce the risk of account compromise even if credentials are phished. 7) Conduct regular security assessments and penetration tests focusing on web application vulnerabilities, including open redirects. 8) Consider disabling or replacing the vulnerable plugin with alternative solutions that do not exhibit this vulnerability if immediate patching is not feasible. 9) Monitor logs for unusual redirect activity or spikes in traffic to untrusted domains originating from the affected systems. These measures, combined, will reduce the attack surface and limit the potential for successful exploitation.
