CVE-2025-13871Network attack vector

File upload via forged resource-management requests

Published Dec 2, 2025 · Updated Dec 2, 2025

Cross-site request forgery in ObjectPlanet Opinio 7.26 rev12562 allows remote attackers to upload files through a connected user's session. The resource-management feature accepts a state-changing file-upload request under the connected user's authority without confirming that the request originated from the application. A connected user must encounter attacker-controlled content, after which the uploaded files are accessible without authentication.
