Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Plate 是一款结合 AI 和 shadcn/ui 的富文本编辑器。在版本 53.3.2 之前，当在服务器端或特权环境中通过 函数将攻击者可控的 HTML 转换为 DOCX 文档时， 会提取并请求远程图片的 URL。该转换过程可能向内部网络资源发起请求，并将获取到的图片数据字节嵌入到生成的 DOCX 文件中，从而导致服务器端请求伪造（SSRF）及响应内容泄露。此外，应用程序还可能因攻击者指定的远程响应而产生额外的资源消耗。该问题已在版本 53.3.2 中得到修复。

Vulnerability Title
Plate: SSRF with response disclosure in DOCX image embedding
Source: CVE Program / CVE List V5
Vulnerability Description
Plate is a rich-text editor with AI and shadcn/ui. Prior to 53.3.2, @platejs/docx-io fetches remote image URLs while converting attacker-controlled HTML through htmlToDocxBlob in a server-side or privileged environment. The converter can make requests to internal network resources and include the fetched image bytes in the generated DOCX, allowing server-side request forgery with response disclosure. Applications can also incur resource consumption from attacker-selected remote responses. This issue is fixed in version 53.3.2.
