AI-suggested

Upgrade all Open WebUI instances to version 0.9.0 or later, where the vulnerability is fixed by adding key prefixing to Redis keys. This prevents key collisions and cross-instance configuration exposure. No additional mitigations are required once upgraded.

Description

CVE-2026-44552 is a vulnerability in open-webui versions prior to 0.9.0 where multiple instances sharing a Redis database can experience key collisions due to unprefixed keys. This causes configuration data from one instance to overwrite another, exposing resource configurations across instances. The issue is fixed in version 0.9.0.
