Open WebUI Allows Viewing of Admin Details

  • Disclosed: 20.03.2025
  • Updated: 11.10.2026 13:18

An improper access control vulnerability in open-webui/open-webui v0.3.8 allows an attacker to view admin details. The application does not verify whether the attacker is an administrator, allowing the attacker to directly call the /api/v1/auths/admin/details interface to retrieve the first admin (owner) details.
