CVE-2023-28848

CSRF protection on user_oidc login returned the expected token in case of an error

Published: Apr 4, 2023Updated: Nov 21, 2024 Sources: CVE List NVDCWE-352

Description

user_oidc is the OIDC connect user backend for Nextcloud, an open source collaboration platform. A vulnerability in versions 1.0.0 until 1.3.0 effectively allowed an attacker to bypass the state protection as they could just copy the expected state token from the first request to their second request. Users should upgrade user_oidc to 1.3.0 to receive a patch for the issue. No known workarounds are available.
