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.

flowintel是flowintel组织开源的一款Web中间件软件。 flowintel 3.3.0及之前版本存在跨站脚本漏洞，该漏洞源于多个用户可控或管理员可控字段的持久化值在Vue编译的DOM元素中渲染时未有效阻止Vue插值表达式注入，可能导致经过身份验证的攻击者注入恶意Vue表达式，成功利用可导致受害者的浏览器中执行任意JavaScript。

Vulnerability Title
Stored Cross-Site Scripting via Vue Template Injection in FlowIntel
Source: CVE Program / CVE List V5
Vulnerability Description
FlowIntel is affected by a stored cross-site scripting vulnerability through multiple user-controlled or administrator-controlled fields. Persisted values—including case titles, ticket identifiers, recurring-case information, user profile attributes, organisation names, and role names—were rendered inside DOM elements subsequently compiled by Vue. Although normal HTML escaping could neutralize direct HTML markup, it did not prevent an attacker from injecting Vue interpolation expressions using the configured [[ ... ]] delimiters. An authenticated attacker able to modify one of the affected fields could store a malicious Vue expression. When another user viewed an affected case, report, profile, recurring-case page, or navigation component, Vue could evaluate the injected expression in the context of the FlowIntel application. Successful exploitation could allow arbitrary JavaScript execution in the victim’s browser under the FlowIntel origin. This could expose information available to the victim, perform actions using the victim’s authenticated session, or modify application data within the victim’s privileges. The patch introduces a dedicated vue_escape filter that escapes HTML-sensitive characters and breaks Vue interpolation delimiters before the values are rendered. The filter is applied to the affected case, account, organisation, role, configuration, and navigation fields.
