{"id":"CVE-2026-97638","state":"PUBLISHED","title":"Forminator Forms <= 1.57.3.1 - Insecure Direct Object Reference to Unauthenticated Arbitrary Draft Deletion and Takeover via 'previous_draft_id' Parameter","description":"The Forminator Forms – Contact Form, Payment Form & Custom Form Builder plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 1.57.3.1 via the 'previous_draft_id' parameter due to missing validation on a user controlled key. This makes it possible for unauthenticated attackers to delete arbitrary saved drafts belonging to other users and take over those draft identifiers by overwriting them with attacker-controlled form submissions. This requires the attacker to have obtained a victim's draft_id, which may be harvested from a shared \"continue later\" link; the nominally present nonce check is effectively bypassed because the nonce is publicly obtainable by any unauthenticated visitor loading a form page.","publishedAt":"2026-10-30T17:15:27.922Z","updatedAt":"2026-10-30T18:08:58.688Z","severity":{"score":7.5,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N","source":"Wordfence"},"assigner":"Wordfence","products":["wpmudev Forminator Forms – Contact Form, Payment Form & Custom Form Builder"],"affected":[{"vendor":"wpmudev","product":"Forminator Forms – Contact Form, Payment Form & Custom Form Builder","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"1.57.3.1","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/61d065d0-d61e-4e65-99ae-eded211681ac?source=cve","https://plugins.trac.wordpress.org/browser/forminator/tags/1.57.3/library/model/class-form-entry-model.php#L3110","https://plugins.trac.wordpress.org/browser/forminator/tags/1.57.3/library/model/class-form-entry-model.php#L429","https://plugins.trac.wordpress.org/browser/forminator/tags/1.57.3/library/modules/custom-forms/front/front-action.php#L1685","https://plugins.trac.wordpress.org/browser/forminator/tags/1.57.3/library/modules/custom-forms/front/front-action.php#L3662","https://plugins.trac.wordpress.org/browser/forminator/tags/1.57.3/library/abstracts/abstract-class-front-action.php#L196","https://plugins.trac.wordpress.org/browser/forminator/tags/1.57.3/library/abstracts/abstract-class-front-action.php#L127","https://plugins.trac.wordpress.org/changeset?reponame=&new=3732192%40forminator%2Ftags%2F1.57.3.1&old=3700727%40forminator%2Ftags%2F1.57.3","https://plugins.trac.wordpress.org/changeset/3732209/forminator/trunk/library/modules/custom-forms/front/front-action.php"],"weaknesses":["CWE-639"],"ingestedAt":"2026-10-30T18:20:07.061Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/97xxx/CVE-2026-97638.json","commit":"55f8edbf9d47efa62275e8ca91bb2e15e821b559","baselineCommit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-97638","state":"PUBLISHED","datePublished":"2026-10-30T17:15:27.922Z","dateUpdated":"2026-10-30T18:08:58.688Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-09-24T17:22:34.939Z"},"containers":{"cna":{"title":"Forminator Forms <= 1.57.3.1 - Insecure Direct Object Reference to Unauthenticated Arbitrary Draft Deletion and Takeover via 'previous_draft_id' Parameter","descriptions":[{"lang":"en","value":"The Forminator Forms – Contact Form, Payment Form & Custom Form Builder plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 1.57.3.1 via the 'previous_draft_id' parameter due to missing validation on a user controlled key.
