Comment 1 Ben Beasley 2026-02-07 07:14:31 UTC 
I’ve proposed a backport of the fix for this CVE in https://src.fedoraproject.org/rpms/rust-jsonwebtoken/pull-request/1. This bug can be closed if that PR is merged and built, and then python-uv-build is rebuilt with the resulting rust-jsonwebtoken package.
Comment 2 Fabio Valentini 2026-02-07 16:05:29 UTC 
Note that python-uv-build does not even depend on rust-jsonwebtoken, so this appears to be a false positive.
