Description Carlos López 2023-08-11 09:01:13 UTC 
CVE-2023-39954

user_oidc provides the OIDC connect user backend for Nextcloud, an open-source
cloud platform. Starting in version 1.0.0 and prior to version 1.3.3, an
attacker that obtained at least read access to a snapshot of the database can
impersonate the Nextcloud server towards linked servers. user_oidc 1.3.3
contains a patch. No known workarounds are available.
