GHSA-6m2c-76ff-6vrf

First published: Fri Mar 14 2025(Updated: )

### Impact A maliciously crafted QPY file containing can potentially execute arbitrary-code embedded in the payload without privilege escalation when deserializing QPY formats < 13. A python process calling Qiskit's `qiskit.qpy.load()` function could potentially execute any arbitrary Python code embedded in the correct place in the binary file as part of a specially constructed payload. ### Patches Fixed in Qiskit 1.4.2 and in Qiskit 2.0.0rc2

Affected Software	Affected Version	How to fix
pip/qiskit	=2.0.0rc1	2.0.0rc2
pip/qiskit	<=1.4.1	1.4.2
pip/qiskit-terra	>=0.18.0<=0.46.3
