Sandboxie 5.26 allows a Sandbox Escape via an "import os" statement, followed by os.system("cmd") or os.system("powershell"), within a .py file.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.43%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
