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...
