CVE-2025-66118: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in BoldGrid Sprout Clients
Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in BoldGrid Sprout Clients sprout-clients allows Reflected XSS.This issue affects Sprout Clients: from n/a through <= 3.2.1.
AI Analysis
Technical Summary
This vulnerability in BoldGrid Sprout Clients (versions up to 3.2.1) involves improper neutralization of input during web page generation, resulting in reflected cross-site scripting (XSS). An attacker can craft malicious input that is reflected in web responses without proper sanitization, enabling script execution in the victim's browser. The CVSS 3.1 score is 7.1, indicating a high severity with network attack vector, low attack complexity, no privileges required, user interaction required, and impacts on confidentiality, integrity, and availability.
Potential Impact
Successful exploitation can allow an attacker to execute arbitrary scripts in the context of the affected web application, potentially leading to theft of user credentials, session hijacking, or other malicious actions impacting confidentiality, integrity, and availability of user data and application functionality. However, no known exploits in the wild have been reported.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no patch or official fix information is provided, users should monitor vendor communications for updates. Until a fix is available, consider applying web application firewall (WAF) rules to detect and block reflected XSS attempts and educate users to avoid clicking suspicious links.
