CVE-2025-2000: Qiskit SDK code execution
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
