Описание
jupyterlab is an extensible environment for interactive and reproducible computing, based on the Jupyter Notebook Architecture. From 4.5.0 until 4.5.10 and 4.6.2, in jupyterlab/extensions/manager.py and jupyterlab/extensions/pypi.py, JupyterLab's PyPI extension manager enforces blocked_extensions_uris by comparing requested install names to blocklist entries with custom normalization that is weaker than PyPI package-name canonicalization. An authenticated user can request a PyPI-equivalent spelling such as JupyterLab.Git for a blocklisted package such as jupyterlab-git, and JupyterLab accepts the install request even though pip resolves the variant to the same package. Security impact requires an allowlist or blocklist intended to restrict package installation, the PyPI Extension Manager, and kernels and terminals that are disabled or delegated to remote hosts. The bypass lets an authenticated user install a prohibited extension, defeat integrity restrictions, and affect availability without gaining new read access. This issue is fixed in versions 4.5.10 and 4.6.2.
A flaw was found in jupyterlab. The PyPI (Python Package Index) extension manager uses a custom normalization process for package names that is weaker than the official PyPI canonicalization. This allows an authenticated user to bypass blocklist restrictions by using an alternative spelling of a prohibited package name. Consequently, an attacker can install unauthorized extensions, compromise system integrity, and impact the availability of the JupyterLab environment.
Отчет
A Moderate impact flaw in JupyterLab's PyPI extension manager allows an authenticated user to bypass extension blocklists. This is due to weak package-name canonicalization, enabling the installation of prohibited extensions by using alternative spellings. This affects the integrity and availability of JupyterLab instances in Red Hat OpenShift AI and Migration Toolkit for Applications when an extension blocklist is actively enforced.
Меры по смягчению последствий
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
