Part-DB 是一个用于电子元器件的开源库存管理系统。在 2.1.2.2 版本之前，Part-DB 使用 Twig 的 过滤器来渲染物料清单（BOM）验证信息消息。这些消息包含已翻译的占位符，其内容由用户控制的物料名称填充。能够编辑物料名称的用户可以将 HTML 标记存入物料名称中。当其他用户导入引用该物料 ID 的 BOM CSV 文件时，恶意的物料名称将以 HTML 形式在受害者的 BOM 验证结果页面中渲染，从而导致跨用户存储型 HTML 注入漏洞。当前的内容安全策略（CSP）似乎阻止了 JavaScrip

Vulnerability Title
Part-DB: Stored HTML injection in BOM validation results via unescaped Part name
Source: CVE Program / CVE List V5
Vulnerability Description
Part-DB is an open source inventory management system for electronic components. Prior to version 2.12.2, Part-DB renders BOM validation information messages using Twig's |raw filter. These messages include translated placeholders populated with user-controlled Part names. A user who can edit a Part name can store HTML markup in the Part name. When another user imports a BOM CSV referencing that Part ID, the malicious Part name is rendered as HTML in the victim's BOM validation result page. This results in a cross-user stored HTML injection issue. JavaScript execution appears to be blocked by the current Content Security Policy, but arbitrary HTML links, forms, images, and CSS-based UI elements can still be injected into a trusted Part-DB page. This issue has been patched in version 2.12.2.
