{"id":"BIT-jupyterlab-2026-73627","summary":"JupyterLab 4.6.0 Plugin Manager Lock-Rule Enforcement Bypass","details":"JupyterLab (pip package 'jupyterlab') versions \u003e=4.1.0,\u003c=4.5.9 and \u003e=4.6.0,\u003c=4.6.1 contain a plugin manager lock-rule enforcement bypass. Two server-side enforcement gaps allow an authenticated user to circumvent administrator lock rules by making direct requests to the /lab/api/plugins endpoint, enabling or disabling plugins that were locked — including child plugins of multi-plugin extensions and plugins locked via the 'lock all' mechanism. This can impact data integrity and bypass hardening or restrictions (e.g., download/upload limits) implemented through locked plugins.
