{"id":"DRUPAL-CONTRIB-2026-165","details":"The Webform module allows site builders to create forms, collect submissions, and configure access to forms and submission data.\n\nWhen Webform is used with JSON:API enabled, submissions may be cached without varying correctly by the authenticated user. If a webform is configured so that authenticated users can view their own submissions, a request to the JSON:API webform submission collection can return a cached response generated for a different user.\n\nThis can allow an authenticated user to view another user's webform submission data through the JSON:API collection endpoint.\n\nThis vulnerability is mitigated by the fact that JSON:API must be enabled, the affected webform must expose submissions through JSON:API, and the attacker must have an account with permission to view their own submissions for the affected webform.","aliases":["CVE-2026-96369"],"modified":"2026-09-23T17:40:57.052394Z","published":"2026-09-23T16:17:08Z","references":[{"type":"WEB","url":"https://www.drupal.org/sa-contrib-2026-165"}],"affected":[{"package":{"name":"drupal/webform","ecosystem":"Packagist:https://packages.drupal.org/8","purl":"pkg:composer/drupal/webform?repository_url=https:%2F%2Fpackages.drupal.org%2F8"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.2.12"}],"database_specific":{"constraint":"\u003c6.2.12"}},{"type":"ECOSYSTEM","events":[{"introduced":"6.3.0"},{"fixed":"6.3.1"}],"database_specific":{"constraint":"\u003e=6.3.0 \u003c6.3.1"}}],"database_specific":{"affected_versions":"\u003c6.2.12 || \u003e=6.3.0 \u003c6.3.1","source":"https://github.com/DrupalSecurityTeam/drupal-advisory-database/blob/main/advisories/webform/DRUPAL-CONTRIB-2026-165.json"}}],"schema_version":"1.9.0","credits":[{"name":"Giuseppe  (giuseppe87)","contact":["https://www.drupal.org/u/giuseppe87"]}]}
