Stirling-PDF is a locally hosted web application that performs various operations on PDF files. In versions prior to 2.5.2, the /api/v1/convert/markdown/pdf endpoint extracts user-supplied ZIP entries without path checks. Any authenticated user can write files outside the intended temporary working directory, leading to arbitrary file write with the privileges of the Stirling-PDF process user (stirlingpdfuser). This can overwrite writable files and compromise data integrity, with further impact depending on writable paths. The issue was fixed in version 2.5.2.
