CVE-2026-112100 Details
Description
A vulnerability was determined in DeepPavlov up to 1.7.0. This affects the function MultiTaskPipelinePreprocessor.__init__ of the file deeppavlov/models/preprocessors/multitask_preprocessor.py. This manipulation of the argument preprocessor causes code injection. The attack is possible to be carried out remotely. The exploit has been publicly disclosed and may be utilized. The project was informed of the problem early through an issue report but has not responded yet.
A code injection vulnerability has been identified in DeepPavlov versions prior to 1.7.0. The issue arises in the MultiTaskPipelinePreprocessor component, specifically within the initialization function, where the 'preprocessor' argument is evaluated using Python's built-in eval() function. This vulnerability allows for arbitrary code execution, as the evaluated string can execute any Python code before returning a valid preprocessor object. The vulnerability can be exploited remotely by crafting a malicious configuration file that is processed by DeepPavlov's model loading functions.
Users are advised to update to DeepPavlov version 1.7.0 or later, where this vulnerability has been addressed.
