CVE-2026-7584 - Arbitrary Code Execution via Unsafe Deserialization in LabOne Q
CVE ID :CVE-2026-7584
Published : May 1, 2026, 7:21 a.m. | 54 minutes ago
Description :The LabOne Q serialization framework uses a class-loading mechanism (import_cls) to dynamically import and instantiate Python classes during deserialization. Prior to the fix, this mechanism accepted arbitrary fully-qualified class names from the serialized data without any validation of the target class or restriction on which modules could be imported. An attacker can craft a serialized experiment file that causes the deserialization engine to import and instantiate arbitrary Python classes with attacker-controlled constructor arguments, resulting in arbitrary code execution in the context of the user running the Python process. Exploitation requires the victim to load a malicious file using LabOne Q's deserialization functions, for example a compromised experiment file shared for collaboration or support purposes.
Severity: 8.4 | HIGH
