Qiskit allows arbitrary code execution decoding QPY format versions < 13

ImpactA 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 correc...

Arbitrary Code Execution (ACE)

Qiskit is vulnerable to Arbitrary Code Execution ACE. The vulnerability is due to unsafe deserialization in the qiskit.qpy.load function, which allows a maliciously crafted QPY file to execute embedded Python code without privilege escalation...

CVE-2025-2000

CVE-2025-2000 describes arbitrary code execution via deserialization of QPY files in Qiskit QPY.load() for formats

Denial Of Service (DoS)

qiskit is vulnerable to Denial Of Service DoS. The vulnerability is due to improper handling of malformed symengine serialization streams within QPY files, allowing an attacker to trigger a segmentation fault in the symengine library using a malicious QPY file...

Deserialization of Untrusted Data

Overview qiskit is an An open-source SDK for working with quantum computers at the level of extended quantum circuits, operators, and primitives. Affected versions of this package are vulnerable to Deserialization of Untrusted Data via the deserialization of QPY files containing malformed symengi...
