CVE-2025-2000 is a critical-severity vulnerability rated 9.8/10 on the CVSS scale. 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.. EPSS estimates a 0.74% chance of exploitation in the next 30 days.
