Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (0.43%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

Description

UltiMaker Cura slicer versions 5.7.0-beta.1 through 5.7.2 are vulnerable to code injection via the 3MF format reader (/plugins/ThreeMFReader.py). The vulnerability arises from improper handling of the drop_to_buildplate property within 3MF files, which are ZIP archives containing the model data. When a 3MF file is loaded in Cura, the value of the drop_to_buildplate property is passed to the Python eval() function without proper sanitization, allowing an attacker to execute arbitrary code by crafting a malicious 3MF file. This vulnerability poses a significant risk as 3MF files are commonly shared via 3D model databases.
