CVE-2021-41094 is a medium-severity flaw (CVSS 4.2) affecting wire. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

Wire is an open source secure messenger. Users of Wire by Bund may bypass the mandatory encryption at rest feature by simply disabling their device passcode. Upon launching, the app will attempt to enable encryption at rest by generating encryption keys via the Secure Enclave, however it will fail silently if no device passcode is set. The user has no indication that encryption at rest is not active since the feature is hidden to them. This issue

wire wire UPGRADE

Affected: >= 3.68 and < 3.70

Fixed in: 3.70

Safe to downgrade to: a release before 3.68

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 3.68 (Debian / Ubuntu)

apt-cache madison wire sudo apt install wire=<VERSION_BEFORE_3.68> sudo apt-mark hold wire

3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list wire sudo dnf downgrade wire-<VERSION_BEFORE_3.68> sudo dnf versionlock add wire

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.
