What is CVE-2025-55151?

The Stirling-PDF web application, responsible for various PDF file operations, has a vulnerability within its 'convert file to pdf' feature. This issue arises from the use of LibreOffice's unoconvert tool for file conversion. Specifically, prior to version 1.1.0, the application is susceptible to server-side request forgery (SSRF) attacks during the conversion process. This could allow an attacker to manipulate requests and access sensitive internal resources. The vulnerability has been addressed in version 1.1.0, emphasizing the importance of keeping applications up to date to mitigate security risks.
