Summary

JupyterLab (pip package 'jupyterlab') versions >=4.1.0, =4.6.0,<=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. Fixed in versions 4.6.2 and 4.5.10.

A flaw was found in JupyterLab. Direct API requests can enable or disable plugins intended to be locked, impacting data integrity and bypassing security restrictions in Red Hat OpenShift AI and Migration Toolkit for Applications deployments.

Red Hat severity: Moderate — CVSS 7.1 (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:H/A:N). Weakness: CWE-414.

Affected Red Hat products: Red Hat OpenShift AI 2.25; Migration Toolkit for Applications 8; Red Hat OpenShift AI (RHOAI). Red Hat fixing advisory: RHSA-2026:65126.

Mitigation checklist

Recommended fix / mitigation
  • Lock each plugin individually with jupyter labextension lock <plugin-id> instead of “lock all” or locking only a parent multi-plugin extension. That is the GHSA workaround until you upgrade.
