Affected: >= 3.0.0 and < 4.1.0

Fixed in: 4.1.0

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 3.0.0 (Debian / Ubuntu)

apt-cache madison wsgidav sudo apt install wsgidav=<VERSION_BEFORE_3.0.0> sudo apt-mark hold wsgidav

dnf --showduplicates list wsgidav sudo dnf downgrade wsgidav-<VERSION_BEFORE_3.0.0> sudo dnf versionlock add wsgidav

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.
