{"id":"DRUPAL-CONTRIB-2021-025","details":"The *Admin Toolbar* (`admin_toolbar`) module extends the default toolbar provided by Drupal Core with various features facilitating day-to-day editorial and administrative work.\n\nThe *Admin Toolbar Search* sub-module of this module\n\n* doesn't sanitize user input in certain cases, which leads to a Cross-Site-Scripting (XSS) vulnerability. An attacker that can create or edit certain entities, entity bundles or entity types may be able to exploit one or more Cross-Site-Scripting (XSS) vulnerabilities to target users with access to the *Admin Toolbar Search* search box, including site admins with privileged access.\n* doesn't properly check access in certain cases, which may result in an information disclosure vulnerability of entity type and bundle labels.\n\nThe vulnerability is mitigated by the facts, that:\n\n* the *Admin Toolbar Search* sub-module must be enabled.\n* an attacker must have one of several permissions, of which at least some are commonly only assigned to either editors, site builders or administrators.\n* a targeted account must have permission to use the search box provided by the *Admin Toolbar Search* sub-module.","modified":"2026-09-10T03:45:12.997455258Z","published":"2021-08-25T14:36:25Z","references":[{"type":"WEB","url":"https://www.drupal.org/sa-contrib-2021-025"}],"affected":[{"package":{"name":"drupal/admin_toolbar","ecosystem":"Packagist:https://packages.drupal.org/8","purl":"pkg:composer/drupal/admin_toolbar?repository_url=https:%2F%2Fpackages.drupal.org%2F8"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.5.0"}],"database_specific":{"constraint":"\u003c2.5.0"}},{"type":"ECOSYSTEM","events":[{"introduced":"3.0.0"},{"last_affected":"3.0.0"}],"database_specific":{"constraint":"3.0.0"}},{"type":"ECOSYSTEM","events":[{"introduced":"3.0.1"},{"last_affected":"3.0.1"}],"database_specific":{"constraint":"3.0.1"}}],"database_specific":{"affected_versions":"\u003c2.5.0 || 3.0.0 || 3.0.1","source":"https://github.com/DrupalSecurityTeam/drupal-advisory-database/blob/main/advisories/admin_toolbar/DRUPAL-CONTRIB-2021-025.json"}}],"schema_version":"1.9.0","credits":[{"name":"Patrick Fey","contact":["https://www.drupal.org/user/998680"]}]}
