CVE-2025-8221 is a cross-site scripting (XSS) vulnerability identified in the JPACookieShop 蛋糕商城JPA版 application developed by jerryshensjf. The vulnerability exists in the goodsSearch function within the GoodsCustController.java file. Specifically, the issue arises from improper handling and sanitization of the 'keyword' parameter, which is susceptible to injection of malicious scripts. An attacker can remotely exploit this vulnerability by crafting a specially designed request that includes malicious JavaScript code in the keyword argument. When the application processes this input and renders it in the response without adequate encoding or sanitization, the malicious script executes in the context of the victim's browser. This can lead to session hijacking, defacement, or redirection to malicious sites. The vulnerability has been publicly disclosed, and while no confirmed exploits in the wild are reported, the availability of proof-of-concept code increases the risk of exploitation. The product uses a rolling release model, which complicates precise version tracking for affected and patched releases. The CVSS 4.0 base score is 5.3 (medium severity), reflecting the network attack vector, no privileges or authentication required, user interaction needed, and limited impact on confidentiality and integrity but no impact on availability.

For European organizations using JPACookieShop 蛋糕商城JPA版, this XSS vulnerability poses a moderate risk. Successful exploitation could allow attackers to steal session cookies, impersonate users, or conduct phishing attacks by injecting malicious scripts into web pages viewed by legitimate users. This can lead to unauthorized access to user accounts, data leakage, and reputational damage. E-commerce platforms are particularly sensitive due to the handling of customer data and payment information. Even though the vulnerability does not directly compromise system availability or integrity, the indirect consequences such as loss of customer trust and potential regulatory penalties under GDPR for insufficient protection of personal data could be significant. The remote exploitability and lack of required privileges increase the attack surface, especially for organizations with public-facing instances of this software.

To mitigate this vulnerability, European organizations should: 1) Immediately review and sanitize all user inputs, especially the 'keyword' parameter in the goodsSearch function, employing context-appropriate output encoding to neutralize malicious scripts. 2) Implement Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in browsers. 3) Conduct thorough code audits focusing on input validation and output encoding across the application. 4) Monitor web application logs for unusual or suspicious requests targeting the goodsSearch endpoint. 5) Engage with the vendor or development team to obtain patches or updates addressing this vulnerability, considering the rolling release model may delay formal patch releases. 6) Educate users and administrators about the risks of XSS and encourage cautious handling of suspicious links or inputs. 7) Employ web application firewalls (WAFs) with rules tailored to detect and block XSS payloads targeting this specific parameter.
