CVE-2026-7584 Details
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.
A vulnerability allowing arbitrary code execution has been identified in the Zurich Instruments LabOne Q serialization framework. This issue arises from an unsafe deserialization process that accepts arbitrary fully-qualified class names from serialized data without proper validation or restrictions. An attacker can exploit this by crafting a malicious experiment file that, when loaded by a user, executes code with the user's privileges. The vulnerability affects LabOne Q versions 2.41.0 prior to 26.1.2, as well as pre-releases 26.4.0b1 through 26.4.0b5. Exploitation requires the victim to deserialize a compromised file, such as one shared for collaboration or support.
Users are advised to update LabOne Q to version 26.1.2 or 26.4.0 and later. The update can be performed via pip. For those who must remain on an earlier version for compatibility, contact Zurich Instruments.
