CVE-2025-54681 is an Open Redirect vulnerability (CWE-601) identified in the CRM Perks Connector for Gravity Forms and Google Sheets, affecting versions up to 1.2.4. This vulnerability allows an attacker to craft URLs that redirect users to untrusted, potentially malicious websites. The flaw arises because the application does not properly validate or restrict the destination URLs in redirection parameters, enabling attackers to exploit this behavior for phishing attacks. When a user clicks on a manipulated link, they are redirected to a site controlled by the attacker, which can be used to harvest credentials, deliver malware, or conduct other social engineering attacks. The vulnerability is remotely exploitable without authentication but requires user interaction (clicking the malicious link). The CVSS v3.1 score is 4.7 (medium severity), reflecting limited confidentiality impact, no integrity or availability impact, ease of exploitation, and the requirement for user interaction. No known exploits are currently reported in the wild, and no patches have been published yet. The vulnerability affects the integration between Gravity Forms and Google Sheets via the CRM Perks Connector, a tool commonly used to automate data transfer between form submissions and spreadsheet records.

For European organizations, this vulnerability poses a moderate risk primarily through phishing campaigns that leverage trusted brand integrations. Organizations using Gravity Forms with the CRM Perks Connector to Google Sheets may inadvertently facilitate attackers redirecting users to malicious sites, undermining user trust and potentially leading to credential theft or malware infections. This can impact sectors with high reliance on web forms for customer interaction, such as e-commerce, financial services, and public sector portals. The confidentiality of user data is at risk if phishing leads to credential compromise. While the vulnerability does not directly affect system integrity or availability, successful phishing can lead to broader security incidents. Given the widespread use of Gravity Forms in Europe and the popularity of Google Sheets for data management, the attack surface is significant. Additionally, GDPR considerations mean that any resulting data breaches or phishing incidents could lead to regulatory scrutiny and fines.

European organizations should implement the following specific mitigations: 1) Immediately audit all instances of the CRM Perks Connector for Gravity Forms and Google Sheets and identify affected versions (up to 1.2.4). 2) Monitor vendor communications closely for patches or updates addressing CVE-2025-54681 and apply them promptly once available. 3) Implement URL validation and filtering at the web application firewall (WAF) or reverse proxy level to detect and block suspicious redirection URLs associated with this connector. 4) Educate users and administrators about the risk of phishing via open redirects, emphasizing caution with links that appear to redirect through trusted domains. 5) Use Content Security Policy (CSP) headers to restrict navigation to trusted domains where feasible. 6) Consider disabling or replacing the vulnerable connector if immediate patching is not possible, or restrict its usage to trusted internal users only. 7) Employ email security solutions with advanced phishing detection to reduce the likelihood of successful phishing campaigns exploiting this vulnerability.
