Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

FacturaScripts 2025.61 版本中存在存储型跨站脚本（XSS）漏洞，原因是"ListAlmacen"接口中的"city"（城市）和"province"（省份）字段未对用户输入进行充分的验证或净化。成功利用该漏洞后，攻击者可在受害用户（即应用程序使用者）的浏览器中执行任意 JavaScript 代码；或者通过执行特制的 JavaScript 代码，将普通用户权限提升为管理员权限，从而破坏系统的机密性，或劫持用户会话（即使启用了 httpOnly 属性，也可通过提取 CSRF 令牌实现会话劫持）。

Vulnerability Title
Multiple vulnerabilities in FacturaScripts
Source: CVE Program / CVE List V5
Vulnerability Description
Stored Cross-Site Scripting (XSS) in FacturaScripts, version 2025.61, caused by a lack of adequate validation or sanitisation of user input in the ‘city’ and ‘province’ fields in the ‘ListAlmacen’ endpoint. Successful exploitation of this vulnerability could allow an attacker to execute arbitrary JavaScript code in the victim’s browser (the application user) or to escalate privileges from a normal user to an administrator by executing specially crafted JavaScript code, thereby compromising the system’s confidentiality or hijacking the session (even with httpOnly cookies by extracting CSRF tokens).
