jupyterlab: PyPI extension blocklist package-name canonicalization bypass
Vulnerability Description
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.

JupyterLab 输入验证错误漏洞
Vulnerability Description
JupyterLab是JupyterLab基金会的一款Web应用开发框架。 JupyterLab 4.5.0至4.5.10之前版本和4.6.0至4.6.2之前版本存在安全漏洞,该漏洞源于JupyterLab的PyPI扩展管理器在比较请求的安装名称与黑名单条目时,使用的自定义规范化弱于PyPI包名规范化,可能导致经过身份验证的用户绕过黑名单安装被禁止的扩展,破坏完整性限制并影响可用性。
