CVE-2025-55150 Details
Description
Stirling-PDF is a locally hosted web application that performs various operations on PDF files. Prior to version 1.1.0, when using the /api/v1/convert/html/pdf endpoint to convert HTML to PDF, the backend calls a third-party tool to process it and includes a sanitizer for security sanitization which can be bypassed and result in SSRF. This issue has been patched in version 1.1.0.
A server-side request forgery (SSRF) vulnerability has been identified in Stirling-PDF versions prior to 1.1.0. The issue arises in the '/api/v1/convert/html/pdf' endpoint, where the application converts HTML to PDF. The backend process involves a third-party sanitizer for security, but flaws in this sanitizer can be bypassed, leading to SSRF. This vulnerability allows the manipulation of URLs that the server-side application can access, potentially leading to unauthorized data exposure or interaction with internal services.
Users can update to Stirling-PDF version 1.1.0 or later, where this vulnerability has been patched.
