As with any other app, we flagged Fennec and Mull with KnownVuln until the app is updated. Contributors fixed the issues that delayed versions 130 and later. Stand by for the build.
@fdroidorg The UX is a bit weird. Recommends to uninstall Fennec immediately due to a vulnerability, but doesn't have a link to/explanation of the vulnerability as far as I can tell.

It would also be nice if F-Droid would mention mitigations that don't require uninstalling Fennec. I would guess that in this case not using Fennec would be enough.
