If a user signs in with a login provider for the first time on the website, a new Drupal user will be created.\n\nA visitor who successfully logs in to their Identity Provider and is denied access to Drupal through custom code or a server error will maintain their session at the Identity Provider, possibly leading to access bypass situations, especially in a shared computing environment.","aliases":["CVE-2026-3531"],"modified":"2026-03-04T19:02:25.349419Z","published":"2026-03-04T18:02:14Z","references":[{"type":"WEB","url":"https://www.drupal.org/sa-contrib-2026-026"}],"affected":[{"package":{"name":"drupal/openid_connect","ecosystem":"Packagist:https://packages.drupal.org/8","purl":"pkg:composer/drupal/openid_connect"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.5.0"}],"database_specific":{"constraint":"\u003c1.5.0"}}],"database_specific":{"affected_versions":"\u003c1.5.0","source":"https://github.com/DrupalSecurityTeam/drupal-advisory-database/blob/main/advisories/openid_connect/DRUPAL-CONTRIB-2026-026.json"}}],"schema_version":"1.7.3","credits":[{"name":"Kimberley Massey (kimberleycgm)","contact":["https://www.drupal.org/u/kimberleycgm"]}]}
