{"id":"CVE-2026-75018","state":"PUBLISHED","title":"Custom Contact Forms <= 7.16 - Missing Authorization to Authenticated (Contributor+) Arbitrary Post Deletion and Post Meta Modification via Nested 'fields[].ID' / 'choices[].ID' Parameters","description":"The Custom Contact Forms plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 7.16. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with contributor-level access and above, to permanently force-delete arbitrary posts of any post type (including pages, administrator-authored posts, and WooCommerce products) and write arbitrary ccf_field_* post meta onto any post regardless of ownership or post type. The top-level form ID is checked via edit_post/publish_posts, but the nested fields[].ID and choices[].ID paths processed by _create_and_map_fields() and _create_and_map_choices() carry no equivalent capability or post-type guard, leaving those sinks fully exposed while delete_item() and delete_submission() contain explicit post-type restriction fixes demonstrating the developer's awareness of scoping requirements.","publishedAt":"2026-09-05T07:38:14.313Z","updatedAt":"2026-09-07T11:17:24.787Z","severity":{"score":4.3,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N","source":"Wordfence"},"assigner":"Wordfence","products":["outlawgt Custom Contact Forms"],"affected":[{"vendor":"outlawgt","product":"Custom Contact Forms","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"7.16","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/9a34ec54-7629-4c14-b5e0-d47f5d3a72ce?source=cve","https://plugins.trac.wordpress.org/browser/custom-contact-forms/tags/7.15.0/classes/class-ccf-api-form-controller.php#L291","https://plugins.trac.wordpress.org/browser/custom-contact-forms/tags/7.15.2/classes/class-ccf-api-form-controller.php#L291","https://plugins.trac.wordpress.org/browser/custom-contact-forms/tags/7.15.2/classes/class-ccf-api-form-controller.php#L336","https://plugins.trac.wordpress.org/browser/custom-contact-forms/tags/7.15.2/classes/class-ccf-api-form-controller.php#L360","https://plugins.trac.wordpress.org/browser/custom-contact-forms/tags/7.15.2/classes/class-ccf-api-form-controller.php#L1026","https://plugins.trac.wordpress.org/browser/custom-contact-forms/tags/7.15.2/classes/class-ccf-api-form-controller.php#L993","https://plugins.trac.wordpress.org/browser/custom-contact-forms/tags/7.15.2/classes/class-ccf-api-form-controller.php#L977","https://plugins.trac.wordpress.org/browser/custom-contact-forms/tags/7.15.0/classes/class-ccf-api-form-controller.php#L336","https://plugins.trac.wordpress.org/browser/custom-contact-forms/tags/7.15.0/classes/class-ccf-api-form-controller.php#L360","https://plugins.trac.wordpress.org/browser/custom-contact-forms/tags/7.15.0/classes/class-ccf-api-form-controller.php#L1026","https://plugins.trac.wordpress.org/browser/custom-contact-forms/tags/7.15.0/classes/class-ccf-api-form-controller.php#L993","https://plugins.trac.wordpress.org/browser/custom-contact-forms/tags/7.15.0/classes/class-ccf-api-form-controller.php#L977","https://plugins.trac.wordpress.org/changeset?reponame=&old=3669565%40custom-contact-forms&new=3669565%40custom-contact-forms"],"weaknesses":["CWE-862"],"ingestedAt":"2026-10-29T20:12:58.252Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/75xxx/CVE-2026-75018.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-75018","state":"PUBLISHED","datePublished":"2026-09-05T07:38:14.313Z","dateUpdated":"2026-09-07T11:17:24.787Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-08-17T13:16:39.258Z"},"containers":{"cna":{"title":"Custom Contact Forms <= 7.16 - Missing Authorization to Authenticated (Contributor+) Arbitrary Post Deletion and Post Meta Modification via Nested 'fields[].ID' / 'choices[].ID' Parameters","descriptions":[{"lang":"en","value":"The Custom Contact Forms plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 7.16.
