MEDIUM (4.3)
user_oidc is an OpenID Connect user backend for Nextcloud. In versions prior to 1.2.1 sensitive information such as the OIDC client credentials and tokens are sent in plain text of HTTP without TLS. Any malicious actor with access to monitor user traffic may have been able to compromise account security. This issue has been addressed in in user_oidc v1.2.1. Users are advised to upgrade. Users unable to upgrade may use https to access Nextcloud. Set an HTTPS discovery URL in the provider settings (in Nextcloud OIDC admin settings).

CVE:CVE-2022-39338 vulnerable 2026-06-03 14:47:51.500870 Stored cross site scripting (XSS) vulnerability via Authorization Endpoint in user_oidc
LOW (3.5)
user_oidc is an OpenID Connect user backend for Nextcloud. Versions prior to 1.2.1 did not properly validate discovery urls which may lead to a stored cross site scripting attack vector. The impact is limited due to the restrictive CSP that is applied on this endpoint. Additionally this vulnerability has only been shown to be exploitable in the Safari web browser. This issue has been addressed in version 1.2.1. Users are advised to upgrade. Users unable to upgrade should urge their users to avoid using the Safari web browser.
