CVE-2023-47268Public exploit

Code execution via project-supplied post-processing command

Published May 8, 2026 · Updated May 8, 2026

Command injection in Prusa Research PrusaSlicer 2.6.1 and earlier allows attackers to execute arbitrary code through a crafted 3MF project. The project-supplied Metadata/Slic3r_PE.config file populates post_process, which PrusaSlicer executes after slicing. Opening or importing the project and exporting G-code triggers the command with the slicing user's privileges on the host.
