{"id":"CVE-2026-3328","state":"PUBLISHED","title":"Frontend Admin by DynamiApps <= 3.28.31 - Authenticated (Editor+) PHP Object Injection via 'post_content' of Admin Form Posts","description":"The Frontend Admin by DynamiApps plugin for WordPress is vulnerable to PHP Object Injection via deserialization of the 'post_content' of admin_form posts in all versions up to, and including, 3.28.31. This is due to the use of WordPress's `maybe_unserialize()` function without class restrictions on user-controllable content stored in admin_form post content. This makes it possible for authenticated attackers, with Editor-level access and above, to inject a PHP Object. The additional presence of a POP chain allows attackers to achieve remote code execution.","publishedAt":"2026-03-26T02:25:19.630Z","updatedAt":"2026-04-08T16:35:48.534Z","severity":{"score":7.2,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H","source":"Wordfence"},"assigner":"Wordfence","products":["shabti Frontend Admin by DynamiApps"],"affected":[{"vendor":"shabti","product":"Frontend Admin by DynamiApps","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"3.28.31","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/0faa8f07-88c1-4638-9de5-e202807866e1?source=cve","https://plugins.trac.wordpress.org/browser/acf-frontend-form-element/trunk/main/admin/admin-pages/forms/settings.php#L419","https://plugins.trac.wordpress.org/browser/acf-frontend-form-element/tags/3.28.27/main/admin/admin-pages/forms/settings.php#L419","https://plugins.trac.wordpress.org/changeset?sfp_email=&sfph_mail=&reponame=&old=3486785%40acf-frontend-form-element&new=3486785%40acf-frontend-form-element&sfp_email=&sfph_mail="],"weaknesses":["CWE-502"],"ingestedAt":"2026-10-29T20:11:50.837Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/3xxx/CVE-2026-3328.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-3328","state":"PUBLISHED","datePublished":"2026-03-26T02:25:19.630Z","dateUpdated":"2026-04-08T16:35:48.534Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-02-27T14:10:06.693Z"},"containers":{"cna":{"title":"Frontend Admin by DynamiApps <= 3.28.31 - Authenticated (Editor+) PHP Object Injection via 'post_content' of Admin Form Posts","descriptions":[{"lang":"en","value":"The Frontend Admin by DynamiApps plugin for WordPress is vulnerable to PHP Object Injection via deserialization of the 'post_content' of admin_form posts in all versions up to, and including, 3.28.31.
