Description
There are packages installed that are affected by a vulnerability referenced in the following CVE:
- Authlib is a Python library which builds OAuth and OpenID Connect servers. From 0.13 until 1.8.0,
authlib.common.security.is_secure_transport() uses a textual prefix comparison for loopback HTTP
exemptions, so a URL whose userinfo begins with a loopback host can be accepted even when its parsed host
is an external non-loopback system. An external party able to supply a URL to OIDC RP-Initiated Logout
registration, authorization-server metadata validation, or another call site can bypass the TLS-required
guard and cause cleartext redirection or acceptance of cleartext endpoints. The issue does not bypass
redirect URI exact matching and does not by itself forge tokens or authenticate users. The vulnerable
authlib.common.security.is_secure_transport() implementation in authlib/common/security.py misinterprets
the userinfo component before OIDC RP-Initiated Logout dynamic client registration and other consumers
enforce transport security. This issue is fixed in version 1.8.0. (CVE-2026-114614)
Solution
Update the open-webui library and its related packages to version 0.12.3-r11 or later.
