CVE-2025-47654 is a high-severity reflected Cross-site Scripting (XSS) vulnerability identified in Adrian Tobey's FormLift for Infusionsoft Web Forms, affecting versions up to 7.5.20. This vulnerability arises due to improper neutralization of user-supplied input during web page generation, classified under CWE-79. Specifically, the web forms fail to adequately sanitize or encode input parameters before reflecting them back in the HTTP response, enabling an attacker to inject malicious scripts. When a victim interacts with a crafted URL or form containing the malicious payload, the injected script executes in the victim's browser context. The CVSS 3.1 base score of 7.1 reflects that the vulnerability can be exploited remotely over the network without requiring authentication (AV:N/AC:L/PR:N), but does require user interaction (UI:R). The scope is changed (S:C), indicating that exploitation can affect components beyond the vulnerable module, potentially impacting confidentiality, integrity, and availability to a limited extent (C:L/I:L/A:L). Although no known exploits are currently reported in the wild, the vulnerability poses a significant risk due to the widespread use of FormLift for Infusionsoft Web Forms in online marketing and customer engagement platforms. Attackers could leverage this vulnerability to perform session hijacking, defacement, phishing, or deliver malware payloads by tricking users into clicking malicious links or submitting crafted forms. The lack of available patches at the time of publication underscores the urgency for affected organizations to implement mitigations promptly.

For European organizations, the impact of this reflected XSS vulnerability can be substantial, especially for businesses relying on FormLift for Infusionsoft Web Forms to capture customer data, manage marketing campaigns, or facilitate e-commerce interactions. Exploitation could lead to unauthorized access to user sessions, theft of sensitive personal data protected under GDPR, and erosion of customer trust. Additionally, successful attacks might enable attackers to redirect users to malicious sites, potentially causing reputational damage and financial loss. Given the interconnected nature of European digital services, a compromised web form could serve as an entry point for broader attacks within an organization's IT environment. The vulnerability's ability to affect confidentiality, integrity, and availability, albeit at a limited level, means that organizations could face regulatory penalties and increased scrutiny if personal data is exposed or manipulated. The requirement for user interaction means that social engineering or phishing campaigns could amplify the risk, targeting employees or customers within Europe.

Since no official patches are currently available, European organizations should implement immediate compensating controls. These include: 1) Employing Web Application Firewalls (WAFs) with custom rules to detect and block typical XSS payloads targeting FormLift web forms. 2) Conducting thorough input validation and output encoding on all user-supplied data before rendering it in web pages, ideally using secure coding libraries or frameworks that enforce context-aware encoding. 3) Educating users and employees about the risks of clicking on suspicious links or submitting forms from untrusted sources to reduce the likelihood of successful social engineering. 4) Monitoring web server logs and application behavior for unusual patterns indicative of attempted XSS exploitation. 5) Isolating and segmenting the web form infrastructure to limit potential lateral movement if exploitation occurs. 6) Planning and testing rapid deployment of patches or updates once they become available from the vendor. 7) Reviewing and updating Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in browsers accessing the vulnerable forms.
