Routine

MEDIUM 6.5UPGRADE

CVE-2026-87014 is a medium-severity flaw (CVSS 6.5) affecting open webui. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

Open WebUI is an extensible, feature-rich, and user-friendly self-hosted AI platform. From 0.9.0 until 0.11.1, role synchronization in backend/open_webui/routers/auths.py and backend/open_webui/utils/oauth.py updated an administrator's database role without invalidating the user record cached by backend/open_webui/socket/main.py. An administrator demoted through a trusted role header or OAuth role mapping could keep an already-open Socket.IO conn

openwebui open webui UPGRADE

Affected: >= 0.9.0 and < 0.11.1

Fixed in: 0.11.1

Safe to downgrade to: a release before 0.9.0

1. Check installed version

apt-cache policy open-webui || rpm -q open-webui || open-webui --version

2. UPGRADE to 0.11.1 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade open-webui

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade open-webui

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 0.9.0 (Debian / Ubuntu)

apt-cache madison open-webui sudo apt install open-webui=<VERSION_BEFORE_0.9.0> sudo apt-mark hold open-webui

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

dnf --showduplicates list open-webui sudo dnf downgrade open-webui-<VERSION_BEFORE_0.9.0> sudo dnf versionlock add open-webui

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.
