This bug appears to have been reported against 'rawhide' during the Fedora Linux 45 development cycle.
Changing version to 45.

Comment 2 Lumír Balhar 2026-10-12 08:36:20 UTC

Fixed in rawhide, f45 and older still affected.

Comment 3 Lumír Balhar 2026-10-14 11:58:15 UTC

I've just created an update for Jupyterlab (to 4.6.3) and related packages for F45 which is going to fix this vulnerability.
