Vulnerability from pysec - Published: 2026-06-29 11:50 - Updated: 2026-07-01 20:23

Details

Impact

A maliciously crafted QPY file 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

CVE-2025-2000 (GCVE-0-2025-2000)

Vulnerability from cvelistv5 – Published: 2025-03-14 13:04 – Updated: 2026-02-26 19:09

Title

Qiskit SDK code execution

Summary

A maliciously crafted QPY file can potential execute arbitrary-code embedded in the payload without privilege escalation when deserialising QPY formats < 13. A python process calling Qiskit 0.18.0 through 1.4.1's `qiskit.qpy.load()` function could potentially execute any arbitrary Python code embedded in the correct place in the binary file as part of specially constructed payload.
