Affected: >= 9.0.0 and < 9.2.15 · >= 10.0.0 and < 10.1.4
Fixed in: 9.2.15, 10.1.4

Note
Distros often backport fixes without changing the version number. Confirm with the distro advisory or changelog.
3. If no update is available yet, DOWNGRADE to a release before 9.0.0 (Debian / Ubuntu)
apt-cache madison traffic-server
sudo apt install traffic-server=<VERSION_BEFORE_9.0.0>
sudo apt-mark hold traffic-server

dnf --showduplicates list traffic-server
sudo dnf downgrade traffic-server-<VERSION_BEFORE_9.0.0>
sudo dnf versionlock add traffic-server
Downgrade risk
Downgrading can break dependent software and may reopen older bugs. Read the distro advisory first and test on a non-production host.
After downgrade
Restart the service, and keep the package held until a fixed release ships.
