Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

JupyterLab versions 4.5.7 through 4.5.10 and 4.6.0 through 4.6.3 are affected, along with notebook 7.5.6 through 7.6.2 and jupyterlite-core 0.7.5 through 0.8.3. When a user clicks a command link in an untrusted Markdown file or notebook and chooses Trust, the trust may be applied to a different document that became current while the prompt was open, so that document's buttons later run without a prompt. Upgrade jupyterlab to 4.5.11 or 4.6.4, notebook to 7.6.3, or jupyterlite-core to 0.8.4. Choosing Run Once instead of Trust avoids the problem until upgrading.
