CVE-2026-4992 Details
Description
A flaw has been found in wandb OpenUI up to 1.0. This affects the function create_share/get_share of the file backend/openui/server.py of the component HTMLAnnotator Component. Executing a manipulation of the argument ID can lead to HTML injection. The attack may be performed from remote. The exploit has been published and may be used. The vendor was contacted early about this disclosure but did not respond in any way.
A vulnerability exists in wandb OpenUI versions prior to 1.0, specifically in the HTMLAnnotator component. The issue arises in the create_share and get_share functions within backend/openui/server.py. These endpoints lack authentication and authorization checks, allowing unauthenticated users to create or overwrite shared components with arbitrary HTML, including scripts. The injected HTML is not sanitized and is rendered in an iframe with allow-same-origin permissions, enabling access to the session cookies of users who view the shared component. This flaw can be exploited remotely, leading to session hijacking and account takeover.
