CVE-2026-27625
HighSummary
Stirling-PDF to lokalnie hostowana aplikacja webowa, która wykonuje różne operacje na plikach PDF. W wersjach przed 2.5.2, punkt końcowy /api/v1/convert/markdown/pdf pozwalał na ekstrakcję wpisów ZIP dostarczonych przez użytkownika bez sprawdzania ścieżek, co umożliwiało zapis plików poza zamierzonym tymczasowym katalogiem roboczym.
Risk Assessment
Każdy uwierzytelniony użytkownik mógł zapisać pliki z uprawnieniami użytkownika procesu Stirling-PDF, co prowadziło do możliwości nadpisania plików i naruszenia integralności danych. Skutki mogą być różne w zależności od zapisywalnych ścieżek.
Recommendation
Zaleca się aktualizację do wersji 2.5.2 lub nowszej, aby usunąć tę podatność i zabezpieczyć aplikację przed nieautoryzowanym dostępem do systemu plików.

Original NVD description (English source)
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.
