CVE-2026-116275 Details
Description
A vulnerability was found in AllenAI AllenNLP up to 2.10.1. This impacts the function Registrable.resolve_class_name of the file allennlp/common/registrable.py of the component Registrable Configuration Machinery. Performing a manipulation of the argument Type results in code injection. The attack may be initiated remotely. The exploit has been made public and could be used. The vendor was contacted early about this disclosure but did not respond in any way. This vulnerability only affects products that are no longer supported by the maintainer.
A vulnerability allowing arbitrary code execution has been identified in AllenAI's AllenNLP versions through 2.10.1. This issue arises from an unsafe reflective instantiation in the 'FromParams' configuration handling, specifically within the 'Registrable' component. The vulnerability is triggered when a model archive containing a crafted 'config.json' is loaded, bypassing validation and executing commands under the privileges of the AllenNLP process.
AllenNLP is no longer actively maintained, and the repository has been archived. Users are advised to migrate to a different framework or isolate their use of AllenNLP. If migration is not possible, run AllenNLP commands in a container with limited privileges and no network access.
