Comment 1 Ben Beasley 2025-11-13 20:55:08 UTC 
Fixed in https://bodhi.fedoraproject.org/updates/FEDORA-2025-10d2e6260b, which backported https://github.com/Kludex/starlette/commit/4ea6e22b489ec388d6004cfbca52dd5b147127c5 to Starlette 0.42.0. Based on available documentation, I believe that this should be a correct and sufficient fix. (Updating Starlette in F41 is not a good option due to incompatible changes and version bounds in dependent packages.)
