PYSEC-2026-491 Apache Pyfory python is vulnerable to deserialization of untrusted data

Deserialization of untrusted data in python in pyfory versions 0.12.0 through 0.12.2, or the legacy pyfury versions from 0.1.0 through 0.10.3: allows arbitrary code execution. An application is vulnerable if it reads pyfory serialized data from untrusted sources. An attacker can craft a data stre...

PYSEC-2026-349 H2O affected by a deserialization vulnerability

A deserialization vulnerability exists in h2oai/h2o-3 versions = 3.46.0.7, allowing attackers to read arbitrary system files and execute arbitrary code. The vulnerability arises from improper handling of JDBC connection parameters, which can be exploited by bypassing regular expression checks and...

PYSEC-2026-510 Qiskit allows arbitrary code execution decoding QPY format versions < 13

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 corre...
