Two server-side enforcement gaps let an authenticated user bypass those controls with direct requests to `/lab/api/plugins`.\n\n### Impact\n\nUsers could workaround the plugin manager lock rules via direct API access for either:\n- child plugins of extensions covering multiple plugins\n- when \"lock all\" was issued by the administrator\n\nThe integrity of data can be impacted, and any hardening or restrictions on permitted user actions (e.g. download/upload limits) within the single-user server can be circumvented if those were implemented with plugins that were locked using the faulty mechanisms.\n\n### Patches\n\nJupyterLab [`v4.6.2`](https://github.com/jupyterlab/jupyterlab/releases/tag/v4.6.2) and [`v4.5.10`](https://github.com/jupyterlab/jupyterlab/releases/tag/v4.5.10) contain the patch.\n\nUsers of applications that depend on JupyterLab, such as Notebook v7+, should update `jupyterlab` package too.\n\n### Workarounds\n\nManually lock all plugins that should be locked. The core plugin identifiers can be found in [the documentation](https://jupyterlab.readthedocs.io/en/latest/extension/extension_points.html#core-plugins) and identifiers for all installed extensions are listed in the [Plugin Manager](https://jupyterlab.readthedocs.io/en/latest/user/extensions.html#managing-plugins-with-plugin-manager).","status":"published","published":"2026-07-22T23:13:34Z","modified":"2026-10-01T03:56:05.514404364Z","cvss":[{"version":"4.0","score":6,"vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:L/VI:H/VA:N/SC:N/SI:N/SA:N","level":"medium"}],"cwes":["CWE-602","CWE-863"],"updated_at":"2026-11-02T15:46:48.546324Z"},{"id":"UBUNTU-CVE-2026-73627","description":"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.
