Arbitrary file write via path traversal in Atril Document Viewer (< 1.26.2)
Atril Document Viewer (default document reader for the MATE desktop environment) prior to version 1.26.2 contains a path traversal vulnerability that enables arbitrary file write. By opening a crafted document, an attacker can cause Atril to write attacker-controlled file contents to an arbitrary filesystem path accessible to the victim user. The described constraint is that existing files cannot be overwritten, but the primitive can still be leveraged to achieve code execution in the context of the user (e.g., by writing new files into locations that influence execution or autostart behavior).
