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.

Stirling-PDF 是一款本地托管的 Web 应用程序，支持对 PDF 文件执行多种操作。在版本 2.13.1 至 2.13.2 期间，POST /api/v1/convert/svg/pdf 接口会通过 Apache Batik 渲染由攻击者提供的 SVG 文件。其中，不带协议方案的根相对图像引用能够绕过 SvgSanitizer.isExternalUrl() 的校验；随后，Batik 会将其相对于 file:///input.svg 文档基址解析为同源的本地文件。在启用清洗（sanitization）的

Vulnerability Title
Stirling-PDF: SVG→PDF local file read (LFI) via SVG-sanitizer and Batik same-origin bypass
Source: CVE Program / CVE List V5
Vulnerability Description
Stirling-PDF is a locally hosted web application that facilitates various operations on PDF files. From 2.13.1 until 2.13.2, the POST /api/v1/convert/svg/pdf endpoint renders attacker-supplied SVG through Apache Batik, and a scheme-less root-relative image reference bypasses SvgSanitizer.isExternalUrl() before Batik resolves it against the file:///input.svg document base as a same-origin local file. The convert() and addSvgAsPage() paths in app/core/src/main/java/stirling/software/SPDF/utils/SvgToPdf.java can then render image-decodable server files into the returned PDF when sanitization is enabled, including without authentication on login-disabled deployments or with non-admin access when login is enabled. The issue discloses PNG, JPG, GIF, or SVG content and provides an existence oracle only for image-decodable paths; plain text, binary files, directories, XInclude text, external entities, explicit file URLs, and tested HTTP references are not disclosed through this mechanism. This issue is fixed in version 2.13.2.
