CyberRota Analysis

AI-Generated

The Open WebUI platform prior to version 0.10.0 is vulnerable to an account enumeration issue at the /api/v1/auths/signin endpoint, where the authentication process is slower for registered accounts compared to non-existent emails. This can be exploited by attackers to identify valid user accounts, potentially leading to unauthorized access. Organizations using affected versions should prioritize upgrading to version 0.10.0 to mitigate this risk.

Original NVD Description

Open WebUI is an extensible, feature-rich, and user-friendly self-hosted AI platform. Prior to 0.10.0, the /api/v1/auths/signin endpoint looked users up by email and only ran bcrypt password verification when a credential existed, making registered-account attempts measurably slower than missing-email attempts and allowing unauthenticated account enumeration. This issue is fixed in version 0.10.0.
